2.3.1 Special Cloning Instructions
It is possible to change Channel 0 values on the portable radio, hold them in a temporary memory,
and download them to the GMH without actually entering them into the permanent memory of the
portable radio. This is convenient for sequential identification numbers used to identify a series of
portables in a radio system. Assuming that the frequencies, Code Guard values, and other Ch 0
values are common for all radios in the system, but that the radio identification number should be
unique to each radio, the following method would be used to clone additional radios for the system.
1. Program the portable radio with all frequencies,
Code Guard values, and Channel 0 values that will
be common to all GMH radios to be cloned.
2. Advance the display to show the portable radio's ID
number-for example, 100.
3. Press the
[CLR]
key; press
125
. Do not press the
[ENT]
key. Now 125 is in temporary memory.
4. Press the
[*]
key, connect the cable to the radios
and download to the GMH by pressing the
[FCN]
key. ID number 125 is now stored in permanent
memory of the GMH.
5. After download, press the
[CLR]
key on the portable
radio. Disconnect the GMH. The portable radio
display will show that 125 is still being held in the
temporary memory of the portable radio.
6. Press the
[PRI]
key. This will increment the ID
number one digit to 126. (Note: any new number can
be entered at this point by pressing the
[CLR]
key
and using the digit keys to enter the new number.)
7. Press the [*] key. Connect the cable to the second
GMH and download by pressing
[FCN]
.
8. Any number of radios can be coded with different or
sequential ID numbers using this technique. The ID
number in the permanent memory of the portable
radio will remain unchanged as 100.
2.3.2 Scan List and Priority Channel Cloning
When a portable radio downloads to an GMH, the
Scan List and Priority Channel designations are also
transferred to the GMH. This includes Priority Mode
and any lockout functions.
To program an GMH with a specific Priority Mode,
Priority Channel, and Scan List along with the
respective lockout functions (if desired), the portable
radio must first be programmed with these
parameters. The lockout functions cannot be held in
temporary memory. See the appropriate operating
procedures in Section 3 for selecting the Scan List,
Priority Channel, and Lockout functions. See
"Priority Scan" on page 2-6 for Priority Mode
selection procedures.
