V90S User Manual
Adjusting squelch
The squelch adjustment allows you to adjust the sensitivity of
the radio so that background noise is minimized. In areas of high
static noise, such as close to large cities, you can improve quality of
reception by adjusting the squelch.
•
Use the
◄
and
►
keys to adjust the level up or down respectively.
•
Adjust the level until the background noise just disappears.
¼
Note:
You can also adjust the sensitivity of the VHF receiver using
the Local/Distance setting. See “Radio sensitivity” on page 108.
Setting transmission power
The V90S has two transmission power settings:
High 25 W (Hi)
Low 1 W (Lo)
To change the power setting:
Press and hold [H/L] until the Hi or Lo icon on the display changes.
¼
Notes:
•
Channel 16 always remains in high transmission power.
•
Some channels allow only low-power transmissions. If you try to
change to high power, the V90S will sound an error beep.
•
Some channels allow only low power transmissions initially, but can
be forced to high power by holding down [H/L] and PTT at the same
time.
•
See “Appendix 7 - Channel charts” on page 119 for a list of channel
data.
