3. Repeatedly press ▲ or ▼ to select
E2-Hi or E2-UHF , then press E .
4. Press DATA . The preset base fre-
quency appears.
5. Enter a desired frequency, then
press E .
6. Press DATA . The preset offset fre-
quency appears.
7. Enter the frequency using the
number keys according to the fol-
lowing guide, then press
E :
• For Motorola Type II VHF, (E2-
Hi band) use 5 kHz steps
between 5 kHz–100 kHz.
• For Motorola Type II UHF, (E2-
UHF band) use 12.5 kHz steps
between 12.5 kHz–100 kHz.
Note: For example, if you pro-
gram 406.0250 as a trunked fre-
quency, the base and offset
frequencies are as follows:
• BASE: 406.0000 MHz, OFFSET:
12.5 kHz=Channel 2
• BASE: 406.0000 MHz, OFFSET:
25.0 kHz=Channel 1
8. Repeat the steps under “Program-
ming Trunked Frequencies” on
Page 32 to store the trunked sys-
tem’s frequencies in your scan-
ner’s banks.
Turning the Motorola
Disconnect Tone Detect
Function On/Off
While trunk scanning a Motorola sys-
tem, your scanner automatically tunes
to the data channel when it detects a
disconnect tone (a code that tells the
trunking system that the transmitter
has finished sending) on the voice
channel.
You can manually turn off this function
so the scanner does not tune to the
data channel under those conditions.
Use this feature to listen to weak
transmissions when conversations are
generally disconnected.
To turn the disconnect tone detect
function off, set the scanner to trunk
track then press
SVC . The scanner
beeps and flashes for about 5
seconds.
Notes:
• To set the scanner so it remains
on the voice channel (even when
a disconnect tone is transmitted or
there is no signal at all) set
SQUELCH so you hear a hissing
noise.
• You cannot use the disconnect
tone detect function if you are pro-
gramming a trunking frequency or
a fleet map.
To set the scanner to automatically
tune to the data channel once again
when it detects a disconnect tone,
press
SVC . disappears.
