|Freelance (shown right) and Freelance II
(shown below) are cordless telephones comprising a matched
handset and mains powered base unit conforming to CTl requirements. Freelance is similar
to Freelance II but does not have an intercom. Freelance is available in
the colours - Alpine White, whilst Freelance II is available in Charcoal
Grey and Polar White.
They offer the following facilities:-
Digital security coding (Handshake)
Approved as prime instrument on DEL with base battery back-up.
PABX compatible (Earth or Timed Break recall)
Dual signalling (switchable from handset)
9 memory stores
Paging between handset and base (Freelance only)
Full Intercom (Freelance II only)
Ringer volume control on handset
Last number redial (up to 50 digits)
Secrecy (microphone mute button)
Battery low warning (handset battery)
Auto Standby (automatically releases the line when handset is put back on the base unit)
Up to 100 Metres radius range between handset and base unit
(N.B. storable characters include all the digits 1-0, pause and pulse/tone, each character
counts as one digit in the memory store).
Made by axon Ltd (Korea)
Freelance and Freelance II are approved as supplied under approval numbers
S/1000/3/L/501907 (Freelance), S/1000/3/L/501908 (Freelance II) for use on Direct Exchange
Lines and PBXs in categories 1,3,5,7,9 & 11.
REN - Freelance and Freelance II have a REN of 1.
Freelance and Freelance II (shown right) are designed for residential or normal office
use, they should be installed away from sources of direct heat, excessive humidity, dust
and vibration. Approximate overall dimensions of both models are 128mm x 245mm x 90mm
weight, 1Kg (Freelance), 1.05 Kg (Freelance II).
A phone socket and 240 Volt, 13 Amp mains socket are required within 3.0 Metres of the
base unit, mains power consumption is approximately 5 Watts.
For maximum radio range the base unit should be mounted away from any sources of Radio
Frequency Interference or structures which may affect radio signals.
When connected to extensions of small PBXs or 2 wire ports of Key Telephone Systems, a 1.7
Mhz Medium Wave RF filter (e.g. Plug in RF filter Item Code 87 7596) may need to be
connected between the cordless telephone and the PBX/KTS.
Cordless telephones can be affected by interference e.g. from fluorescent lights or
electrical appliances and range can be reduced by the screening effects of building
structures e.g. steel framework, foil backed wallboards. There are 8 pairs of frequencies
allocated for CT 1 cordless telephony use, interference or overhearing may occur where
other cordless telephones on the same or adjacent channels are located nearby. In such
cases Freelance and Freelance II should be selected to have the greatest (at least two)
channel difference from any other nearby CT1 cordless telephones.
Description BT Item Code
Freelance II 870460

Aerial 870462 (handset telescopic aerial)
Batteries 870461 (rechargeable batteries for handset)
N.B. Freelance and Freelance II are intended for customer installation. The radio
channel number is identified by labels on the box, handset and base (but not by item code
number which is the same for all channels). On Freelance and Freelance II the channel will
be marked by a number in the range 1 - B (the 8 channels are available for all CT1
telephones, other models may be marked in the range A - H instead). The channel labelling
must be checked where a particular frequency is requested e.g. to avoid interference from
a neighbouring CT1 telephone.
Idle - Normal capacitor loop. Freelance and Freelance II do not draw on-hook current.
Seized - Normal loop.
Freelance and Freelance II handset and base units are matched together by their security
code signal handshake. The security coding prevents unauthorised access to the line by
other cordless telephone users, the handshake is created at one second intervals during
calls to ensure chat only the matched handset controls the call. There are over 65,000
security codes, these are fixed on manufacture hence handsets and base units should be
regarded as matched pairs and not separated, additional or replacement handsets are not
Use on PBXs and Key Telephone Systems (with 2-wire ports)
Freelance & Freelance II unlike Freeway are also approved for use as extensions to
switching systems (PBXs approval in categories 1,3,5,7,9 & 11). As with other CT1
cordless telephones, some of the 1.7MHz signal from the base unit may be picked up by the
switching system causing system mis-operation. No problems have been found when used on
Medium & Large PBXs. The following compatibility notes based on test results are for
guidance when Freelance & Freelance II are to be used on smaller BT supplied switching
TSX50/Viceroy/Kinsman. - no problems except not to be used on Superslic ports.
Pentara/Herald/Ensign. - no problems.
Consort - no problems.
Navigator - no problems.
Escort - Connect only via a Plug in RFI filter on a 2 wire extension (if without Escort
key module) on extension 1 or 3.
Minimaster 3 - via a plug in RFI filter.
Renown/208H - via BT 80RF2 fitted adjacent to CCU.
AMBASSADOR ESS/Senator (via External Extension adapter SA 10253) - via BT 80RF2 (fitted
adjacent to SA 10253) and 'Plug in RFI adapter' at Freelance base unit. The Freelance base
unit must be at least 10 Metres from the AESS/Senator CCU and SA 10253 adapter.
Where problems do occur, a Plug in RFI filter at the Freelance LJU should first be tried.
If this is not successful then a BT 80 RF2 tried at the CCU end of the extension cabling
instead, also ensure Freelance base unit is kept well away from the switching system CCU
Incoming ringing signal
To comply with user safety requirements for prevention of acoustic shock, the tone caller
out put is regulated and builds up in volume over 4 bursts of ringing. The incoming ring
signal sequence involves a security 'handshake' resulting in the handset ring bursts not
coinciding with ringing at the base unit or other telephones on the line. If is a feature
of these cordless telephones that uneven ringing bursts can occur, depending on the
cadence of the ringing.
Base unit batteries
It is a condition of CT1 approval that if used as the 'sole' (prime) instrument on a DEL,
outgoing emergency calls must be possible in mains tail, to enable this 6 AA size cells
(Leakproof Alkaline type preferred) must be fitted (users responsibility) in the base
Radio power output
To comply with CT1 requirements, the effective radiated power (ERP) transmitted by the
handset or base unit must not exceed 10 milliwatts, the Base unit transmits 1.7Mhz signals
from the loose wire aerial to the ferrite aerial inside the handset and the handset
transmits 47Mhz signals from the telescopic aerial to the base unit telescopic aerial.
Calls on any CT1 telephones are not secure from overhearing and may be picked up by other
cordless telephones operating on the same frequencies or by Medium Wave radio receivers,
Freelance and Freelance II will clear down calls if the 'handshake' is affected by an
Intercom calls are limited by regulations, a warning bleep will be heard 3 Seconds before
Intercom call is automatically cut off at 2 Minutes and 40 Seconds. Intercom cannot be set up
again until a full minute has elapsed since the end of a previous intercom call.
Freelance and Freelance II require charging 24 hours for a full charge, fully charged
batteries should in practice give 12 hours use in 'Talk' mode in a day or 30 Hours in
'receive' Mode. The handset will emit a slow 'bleep' in 'Talk mode when batteries need
recharging. Users are recommended to leave the handset on charge over night in normal use.
Battery capacity can be expected to reduce after 2 years.
