No sound comes from the
speaker.
• Volume level is too low.
• The squelch level is set too tight.
• A selective call or squelch function is activated
such as pocket beep or tone squelch.
• Rotate [VOL] clockwise.
• Set the squelch level to the threshold.
• Turn the appropriate function OFF.

Sensitivity is low and only
strong signals are audible.
• Antenna feedline or the antenna connector sol-
der has a poor contact or is short circuited.
• Check, and if necessary, replace the feedline or
solder the antenna connector again.
p. 14
No contact possible with an-
other station.
• The transceiver is set to semi-duplex.
• The other station is using tone squelch.
• Set to simplex.
• Turn ON the tone squelch function.

p. 51
Repeater cannot be ac-
cessed.
• Wrong offset frequency is programmed.
• Wrong subaudible tone frequency is pro-
grammed.
• Correct the offset frequency.
• Correct the subaudible tone frequency.
p. 27
p. 26
Frequency cannot be set.
• The frequency lock function is activated.
• Priority watch is paused on the watching fre-
quency.
• Turn the function OFF.
• Push [(M/CALL)PRIO] to resume the watch.
p. 16
p. 45
Frequency cannot be set via
the microphone.
• The frequency lock function is activated.
• The microphone keypad lock function is acti-
vated.
• Priority watch is paused on the watching fre-
quency.
• Push and hold to deactivate the fre-
quency lock function.
• Push [FUNC], then [A16KEY LOCK] to deacti-
