Squelch

The PSR-800 is equipped with a top mounted squelch control.
The squelch control acts as a gate for the transmissions that
PSR-800 receives. When the squelch control is rotated fully
clockwise, only stronger signals will pass through the squelch
gate, and weaker signals may not be received. When the
squelch is rotated fully counterclockwise, the squelch gate will be
open even when no signal is present, causing PSR-800 to
operate slowly or to stop on objects where no transmission is
present, playing noise only. The PSR-800 works best when the
gate is set so that it is closed when no transmissions are present,
but able to open when a desired transmission occurs.
The ideal setting for the squelch control is between 10 and 11
oʼclock.

If you find that you are missing some transmissions, try setting
the squelch control further counterclockwise. If you find that the
PSR-800 seems to be scanning very slowly or stopping on
frequencies with noise only, rotate the squelch control clockwise
until normal scanning resumes.

Understanding the Display

Your PSR-800 features a high contrast, backlit Liquid Crystal
Display (LCD) to provide you with information about the status of
the PSR-800 while you are using it. A menu-driven user interface
provides access to the settings that control what the PSR-800
monitors. Figure 4 shows an example of an PSR-800 menu.

operate PSR-800 with alkaline batteries if the Battery Type
Selection switch is set to the NiMH position. Doing so may
result in battery leakage or other damage to your scanner if the
scanner is connected to an external power source. !
