setting it UP
Even though you can change your radio's settings at any time, you will probably want to
establish initial settings when you have turned it on for the first time. You will adjust some
of these settings on an as-needed basis, but some settings might only be set once and not
need adjustment at all.
Acquiring GPS Location
The MHS235 automatically acquires your current GPS location when it is turned on. Turn
on the radio and point the antenna towards the sky. It will triangulate your location and save
it.
Do not let anything obstruct the antenna, such as a metal cabin ceiling.

Changing the Volume
To change the speaker volume, press VOL/SQ to enter Volume Setting mode.The VOL and
SQ icons display at the bottom of the screen (VOL blinks). Press Channel Up or Channel
Down to increase or decrease the volume levels (0 - 15).
Setting the Squelch Level
The MHS235 recognizes signals as transmissions if they exceed a signal strength
threshold. Adjusting the squelch sets this threshold level. Increasing squelch requires a
signal to be stronger to be seen as a transmission. If you set the squelch too high, you
will risk not receiving transmissions that are lower than that threshold. Reducing the
squelch allows weaker signals to be accepted. However, if you lower the squelch too
much, you will hear white noise all the time.
The squelch feature reduces static on the speaker by filtering out any background
channel noise. At the lowest squelch level, the speaker plays all signals, including any
channel noise. Setting the squelch level higher filters out noise and lets only actual radio
transmissions through.
While listening to a channel, press and hold VOL/SQ to enter Squelch Setting mode. The
VOL and SQ icons display at the bottom of the screen (SQ blinks). Press Channel Up or
Channel Down to increase or decrease the squelch levels (0 - 15).
note: setting the squelch level too high may prevent you from hearing weaker transmissions.

if you are having difficulty hearing a transmission, try setting the squelch level lower.
