Checking Out The System
• Ensure that all the phones are operative, set to Tone and Timed break recall (usually
marked as T, TB, DTMF& TBR,MF&TBR). Please note that the Multi 5 does not support
the use of phones which are PULSE, LOOP DISCONNECT (LD) or EARTH RECALL(E,
ER).
• Check there are no wiring mistakes and that all the extension phones are plugged in.
• Plug in the Multi 5 ac mains lead and switch on. Do not plug into the exchange line master
socket yet.
• Make an internal call from one extension to another.
• Ensure that the ringer works correctly and that the speech is clear and noise free. Repeat
this procedure to check all the extensions.
• Switch off the power to the Multi 5 and plug the exchange line cord into the exchange line
master jack socket.
• Lift the handset at extension 1 - you should hear the public exchange dial tone. Now make
an outside call to check the exchange line. Replace handset.
• Switch on the mains power again.
• Make another outside call from extension 1. This time dial 9 followed by the external
number. Refer to Using the Multi 5 section of this handbook.
If a fault is found during the above, switch off the mains power, remove the exchange line cord
from its socket and check that the wiring is correct.
Under no circumstances must the cover of the Multi 5 be removed without first
disconnecting the ac mains and the exchange line cord, and must be replaced before
reconnecting the ac mains and the exchange line cord.
