5-5 Monitor function
The Monitor function forces the squelch to open. When receiving signals are
relatively weak or are often interrupted, it opens the squelch temporarily, re-
gardless of the current squelch level. This function is activated when the "Monitor
key operation setting" (P. 87) is set to the Monitor function.
There are two options for the Monitor function: PUSH and HOLD. When the
[MONI] key is pressed, both options open the squelch and the "BUSY" appears
on the LCD.
• For the procedure to switch between PUSH and HOLD, refer to "Monitor key
operation setting" (P. 87)
• When PUSH is selected, the squelch opens only while the [MONI] key is held
down. When the [MONI] key is released, the squelch returns to the original
level.
• When HOLD is selected, the squelch remains open once the [MONI] key is
pressed. When the [MONI] key is pressed again, the squelch returns to the
original level.
• When the Monitor function is used, the Tone Squelch and DCS func-
tions is also disabled temporarily.
MEMO
• If you cannot receive any signals and suspect a malfunction, use this
function to check if the receiver can receive signals properly.
5-6 Mute Function
The Mute function silences sounds. It cuts off audio outputs even when signals
are received. This function is activated when the "MONI key setting" (P. 87) is
set to the Mute function. This function is useful when you want to silence the
sound with one key touch without adjusting the volume.
There are two options for activating the Mute function: PUSH and HOLD. When
the [MONI] key is pressed, either option activates the Mute function and "MUTE"
illuminates on the LCD.
• Only one of the Monitor function and Mute function can be selected at
a time.
