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 same installation.
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 effective.
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).
