Using Your Radio
Turning It On
Press and hold WX/POWER for at least two seconds to turn the radio on.
Press and hold WX/POWER again to turn the unit off.
Setting It Up
Even though you can change your radio’s settings at anytime, you will
probably want to establish initial settings after you have turned it on for the
fi rst time. You will adjust some of these settings on an as-needed basis, but
some settings might only need to be set once.
Changing the Volume
To change the speaker volume, press VOL/TX PWR to enter Volume Setting
mode. 0 (for volume level 0 - 15) displays. Press CHANNEL UP or CHANNEL
DOWN to increase or decrease the volume levels. Press VOL/TX PWR to
save.
Setting the Squelch level
The MHS115 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.
While listening to a channel, press SQL/UIC to enter Squelch Setting mode.
The SQUELCH Level (S0) number displays on the LCD. Press CHANNEL UP
or CHANNEL DOWN to increase or decrease the squelch levels (0 - 3). Press
SQL/UIC to save the setting.
