battery compartment. The Battery Type Selection switch is used to select standard

disposable alkaline batteries or rechargeable NiMH batteries. Setting the Battery Type

Selection switch to the correct option for the batteries you are using selects the appropriate

low battery detection threshold for the type of batteries in use and enables in-radio

charging for rechargeable NiMH batteries.

WARNING: Never operate iSCAN with alkaline batteries if the Battery Type Selection

switch is set to the NI-MH position. Doing so may result in battery leakage or other damage

to your scanner if the scanner is connected to an external power source.

Squelch

iSCAN is equipped with a top mounted squelch control. The squelch control acts as a gate

for the transmissions that iSCAN 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 iSCAN to operate slowly or to stop on

objects where no transmission is present, playing noise only.

The ideal setting for the squelch control is between 11 and 12 o’clock. If you find that you

are missing some transmissions, try setting the squelch control further counterclockwise. If

you find that iSCAN seems to be scanning very slowly or stopping on frequencies with

noise only, rotate the squelch control clockwise until normal scanning resumes again.

Understanding the Display

Your iSCAN features a high contrast, backlit Liquid Crystal Display (LCD) to provide you

with information about the status of iSCAN while you are using it. A menu-driven user

interface provides access to the settings that control what iSCAN monitors. Figure 3 shows

an example of an iSCAN menu.
