APPROVAL STATUS
Freelance 100 and Freelance 200 are approved as supplied under approval. numbers
S/1000/3/N/502433 (Freelance 100), S/1000/3/N/502434 (Freelance 200) for use on Direct
Exchange Lines and PBXs in categories 1,3,5,7,9 & 11. REN, Freelance 100 and Freelance
200 have a REN of 1.
Freelance 100 (shown to the right) and Freelance 200 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 100), 1.05 Kg (Freelance 200).
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. In domestic premises
locating the base unit in an upstairs room will give better range than at ground level.
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 100 and Freelance 200 should be selected to
have the greatest (at least two) channel difference from any other nearby CT1 cordless
telephones.
INSTALLATION/COMMISSIONING
Freelance 100 and Freelance 200 were intended for retail sale and customer installation
only. Installation instructions were included in the product user guide and involve:-
Inserting (customer provided) batteries in base unit (if to be used as prime instrument)
Siting the base unit within reach of a phone socket and mains socket where it will give
maximum range.
Setting the channel switch (A or B. Base and handset to same setting).
Setting recall switch on base of unit (E for Earth recall PBXs or TB for Timed Break
recall PBXs or for Star Services on DELs).
Although the handset batteries may have enough power to make a simple functional test, the
handset should be charged for 24 hours before full use.

Description BT Item Code
Freelance 100 870516
Freelance 200 870518
Plug in RFI Filter 877596
BT 80A RF2 870157
Aerial (handset telescopic aerial) 870462
Batteries 870461
(rechargeable batteries for handset)
N.B. Freelance 100 and Freelance 200 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 100 and Freelance 200 the channel
will be marked by a number in the range 1 - 8 (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 CTI telephone.
LINE TESTING Idle - Normal capacitor loop. Freelance 100 and Freelance
200 do not draw on-hook current.
Seized - Normal loop.
INFORMATION
Security codes
Freelance 100 and Freelance 200 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 repeated at one second intervals
during calls to ensure that 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
available.
Use on PBXs and Key Telephone Systems (with 2-wire ports).
Freelance 100 & Freelance 200 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 misoperation.
No problems have been found when used on Medium & Large PBXS. The following
compatibility notes based on test results are for guidance when Freelance 100 &
Freelance 200 are to be used on smaller BT supplied switching systems:-
TSX50/Viceroy/Kinsman - no problems except not to be used on Superslic ports.
Pentara/Herald/Ensign - no problems
Escort - Connect only via a 'Plug in RFI filter' on a '2 wire' extension (i.e. without
Escort key module) on extension 1 or 3.
Minimaster 3 - via a BT plug in RFI filter.
Renown/208H via BT 8O/RF2 fitted adjacent to CCU.
AESS/Senator (via External Extension adapter SA 10253) - via BT 8O/RF2 (fitted adjacent to
SA 10253) and BT Plug in RFI adapter at Freelance 100 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 8O 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
and cabling.
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. It is a feature
of these cordless telephones that uneven ringing bursts can occur, depending on the
cadence of incoming ringing signals.
Base unit batteries
It is a condition of CT1 approval that it used as the sole (prime) instrument on a DEL,
outgoing emergency calls must be possible in mains fail, to enable this 6 AA size cells
(Leakproof Alkaline type preferred) must be fitted (users responsibility) in the base
unit.
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.
Overhearing
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 100 and Freelance 200 will cleardown calls if the handshake is affected by an
interfering call.
Intercom regulations
Intercom calls are limited by regulations, a warning bleep will be heard 30 Seconds before
Intercom call is automatically cut off at 2 Minutes and 40 Secs. Intercom cannot be set up
again until a full minute has elapsed since the end of a previous intercom call.
Battery charging
Freelance 100 and Freelance 200 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 or Receive 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 use.
