F) TROUBLE SHOOTING
1) YOUR RADIO WILL NOT TRANSMIT OR YOUR TRANSMISSION
IS OF POOR QUALITY
-
Check that the antenna is correctly connected and that the SWR is properly
adjusted.
-
Check that the microphone is properly plugged in.
English
-
Check that the
RF POWER
value is set on maximum.
(See §
RF POWER
page
22)
.
-
Check that the
MIC GAIN
value is set on maximum.
(See §
MIC GAIN
page
22)
.
2) YOUR RADIO WILL NOT RECEIVE OR RECEPTION IS POOR
-
Check that the squelch level is properly adjusted.
-
Check that the volume (
1
) is set to a comfortable listening level.
-
Check that the antenna is correctly connected and that the SWR is properly
adjusted.
-
Check that you are using the same modulation mode as your correspond-
ent.
-
Check that the
RF GAIN
level is set on maximum.
(See §
RF GAIN
page
22)
.
3) YOUR RADIO WILL NOT LIGHT UP
-
Check the power supply.
-
Check the connection wiring.
-
Check the fuse.
G) HOW TO TRANSMIT OR RECEIVE A MESSAGE ?
Now that you have read the manual, make sure that your transceiver is
ready for use (i.e. check that your antenna is connected).
Press the «push-to-talk» switch (
17
) and announce your message «Attention
stations, transmission testing» which will allow you to check the clearness
and the power of your signal. Release the switch and wait for a reply. You
should receive a reply like, «Strong and clear».
If you use a calling channel (19) and you have established communication
with someone, it is common practice to choose another available channel
so as not to block the calling channel.
