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 first 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/LOCK 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/LOCK to save.

Setting the Squelch level

The MHS157 recognizes signals as transmissions if they exceed a
signal strength threshold.
Strong signals
Weak signals
Noise
No Medium High
Squelch Squelch
Squelch
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 and hold BAND/MENU to enter the
Menu. Press ENT/L/M/H till you enter the Squelch menu mode.The
Squelch level number displays on the LCD. Press CHANNEL UP or
CHANNEL DOWN to increase or decrease the squelch levels (0 - 3).
Press ENT/L/M/H to save the setting.
