Keytones and Brightness
Your scanner features a backlit keypad and display for easy viewing
and sounds a tone each time you press a key.
To set the keytone:
1. Turn on the scanner.
“Multi-system Trunking Scanner”
appears.
2. While
“Multi-system Trunking Scanner”
remains on
screen, press 1 to turn on the keytone or 2 to turn it off.
To change the backlight mode:
Repeatedly press DIM to adjust display backlight brightness to
dim, off, or bright.
Delay
Sometimes several seconds can pass between transmissions. To
avoid missing a reply, a delay is automatically set for each channel.
The scanner pauses for 2 seconds after a transmission stops before
it resumes scanning or searching.
To turn the delay on and off:
1. Press
•
/DELAY.
“DLY”
appears if the delay is on.
2. To turn on the delay, press
•
/DELAY again.
“dly”
appears if the
delay is off.
Squelch and Attenuator
The squelch and attenuator control the scanner sensitivity. If you
hear a hissing noise, the scanner will remain on the current channel.
To set squelch:
1. Turn SQUELCH down (counterclockwise) until you hear noise.
2. Turn SQUELCH up (clockwise) a little past where the noise
stops. The higher the squelch is set, the stronger the signal
required to break the squelch.
3. If noise starts breaking the squelch, turn SQUELCH up to
decrease the scanner’s sensitivity. To hear weaker signals, turn
SQUELCH down to increase its sensitivity.
With the attenuator on, the scanner might not receive weak signals,
but immunity to adjacent strong signals is improved.
You can reduce interference using two attenuator modes:
• Global – (Default) The attenuator setting is applied to all
channels, bands, or groups.
• Normal – Lets you set the attenuator in each channel, band,
or group.
Note: You cannot set the attenuator while scanning.
To set the attenuator mode:
1. To set Global mode, press FUNC and then ATT. On the display
“G”
appears.”
2. To set Normal mode, press FUNC and then ATT. On the display
“G”
disappears.
Then for each channel:
• On – Press ATT.
“A”
appears.
• Off – Press ATT again.
“A”
disappears.”
