The BT Freeway (Cordless Telephone
No. 3 A-H) comprises a handset and mains powered base unit. The handset
can be used up to 100 metres away from the base unit under ideal conditions, and
communicates via a radio link to the base unit. Facilities of Cordless Tele 3 A-H

The base unit incorporates a two metre wire aerial for base to handset signalling and a
telescopic aerial for handset to base signalling. The handset incorporates an internal
aerial for base to handset signalling and a telescopic aerial for handset to base
signalling and a set of rechargeable batteries to power the handset.

The Freeway cost £100 in the early 1980's.
Cordless Telephones 3 A-H are covered by CTI approval and may only be used as extension
instruments on DELs, they are not approved for use as the sole instrument on a DEL or for
PBX extension use.
Cordless Telephones 3 A-H each have a Ringer Equivalence Number (REN) of 0.5. Telephone
instruments (BT and non BT supplied) are now required to be labelled with their REN so
that users do not exceed the permitted maximum number of ringers in circuit.
A telephone with a REN of 1 has a ringer sensitivity similar to that of a standard
instrument (Tele 8746G), the total REN value of all ringers connected at any time at an
installation must not exceed 4.
The REN does not guarantee compatibility between ringers of different technologies on the
The effective range of Cordless Telephones 3 A-H between handset and base unit is greatly
dependant on base unit location and aerial positioning.
The choice of location should take into consideration that walls and electrical equipment
may have a screening effect that can adversely affect the radio signals between handset
and base unit. For maximum effect, base unit aerials should be fully extended vertically.
The base unit should not be plugged into the same mains socket as equipment (e.g.
refrigerators) that can cause electrical interference.
The base unit incorporates keyhole screw holes to facilitate wall mounting if required.
Functional testing includes carrying out the checks listed in the user guide as follows:-
PROBLEM CHECK LIST
NO DIAL TONE
1. Mains power is on
2. RECEIVE/TALK switch is in 'TALK' position.
3. ON/OFF switch is switched to 'ON'
4. Battery low indicator. This will only light up when the battery is running low, if
battery power is totally drained this will not glow and the handset will appear dead. The
Handset should be put on charge.
5. Telephone line cord is plugged into socket and is still attached to the Base-Unit.
1. Check the above items BUT ensure that the CALL RECEIVE/TALK switch is in the 'RECEIVE'
position. If left in TALK incoming calls will NOT ring.
INTERFERENCE DURING CALLS
1. Distance from Base-unit. If speech quality is poor, DURING CALLS moving nearer the Base
will improve reception.
2. Battery power is low. Recharge the Handset at the Base-unit.
3. Base-unit is situated close to a source of interference. Move the base to another
location. A high position is recommended for best performance.
4. Interference from objects near the Handset e.g. TVs, fluorescent lights. Move the
Handset away from the interference.
5. Check that the aerials are fully extended.
If after checking all the above Freeway does not operate the following actions may be
a. Disconnect the mains power and unplug the telephone
b. Turn the ON/OFF switch on the Handset to 'OFF'
c. Leave the unit disconnected for at least one minute (ideally 5-10 mins).
d. Re-connect the mains lead and telephone line, turn the Handset ON/OFF switch to 'ON'
and check again if the Freeway will operate.
The above procedure has been found to be an elective method of discharging any
electrostatic charge that may have accumulated on the instrument.
If it is necessary to maintenance exchange or recover a Cordless Telephones 3 A-H, the
on-off switch (near the receive-talk switch) must be switched to OFF to prevent total
discharge to the Nickel Cadmium battery in the handset.
New Cordless Telephones 3 A-H carry an 18 month BT CPE Warranty from the date of manufacture
as shown on the base of the instrument (year and week marking forming the first 4 digits
of the 11 digit serial number).

Idle - Normal Capacitor Loop test conditions via the master socket and tone caller/bell
circuit of the associated telephone.
Seized:- Transmission and Pulsing Loop is via non-resistive components and pulsing relay
contacts. The loop should test approximately 250 ohms at 30 ma loop current.
The handset incorporates a Battery low indicator, this will light up when the battery is
running low and will extinguish if the battery becomes discharged. To avoid damage to the
batteries these should not be left in a discharged state.
A plug-type transformer type power unit is available for use with handsets that are likely
to be used extensively away from the base unit. Customers may purchase these direct from

There is a screw control in the underside of the base unit, this is not referred to in
user guides, is set on manufacture and should not be touched.
Cordless Telephones operating on the same frequencies may interfere with each other if
used in neighbouring locations, this interference may be in the form of cutting into
established conversations or noise.
Calls on Cordless Telephones (including Cordless Telephones 3 A-H) 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.
Cordless Telephones 3 A-H incorporate a coded signalling system (security code) to ensure
that each base unit will only seize the line when signalling by its own handset and each
handset will only ring to incoming calls when signalled by its own base unit.
Hence Cordless Telephones 3 A-H must only be supplied and recovered as matched pairs i.e.
the serial number on the base unit must be the same as on the handset.
