1. Turn on both scanners.
2. Connect the supplied clone cable to each scanner’s PC/IF jack. *CLONE MODE* UP to send, remove
cable to exit appears.
3. Press /¥. Confirm send data? 1=Yes Press other key for No. appears.
4. Press 1 to send the data to the other unit or press any other key to cancel the operation.
The scanner sends the data. To exit the clone mode, remove the cable.
Trunking Operation
The scanner tracks transmissions that use the Motorola® Type I and Type II (such as Smartnet and
Privacy Plus) and hybrid analog trunking systems, plus GE/Ericsson (EDACS) type systems, which are
extensively used in many communication systems.
Trunking systems allocate a few frequencies to many different users. When the mobile unit transmits a
signal, one frequency is chosen from among the allocated frequencies in that trunking system. The user’s
ID talk group is sent with the signal.
To receive trunking signals, you must store all the trunking group frequencies in one bank (see “Storing
Known Frequencies into Channels” on Page XX) and input ID codes in the ID memory (see “Storing Talk
Group IDs” on Page XX).
Important : To listen to the transmission, the mode of the programmed channel must be the same as that of
the trunking channel (MO, or ED).
When an ID code is received, the ID list for the bank is searched, and if found, the text name stored for the
ID appears. If not found, scanning resumes immediately unless the bank is in open trunking mode.
Note: There might be more than one talk group transmitting at a time in some Motorola trunking systems. If
you set the scanner to manually tune in Motorola trunking mode, you will hear the talk group on that
channel, but the display will alternate between all active IDs.
Trunking group frequencies are included in the supplied Police Call Trunking Guide. Frequency fleet map
and talk group information is also widely available on the Internet, at www.trunkscanner.com for example.
UNDERSTANDING TRUNKING
In the past, groups that transmit frequently, such as police departments, could transmit on only a few
frequencies. This resulted in heavy traffic and often required 2-way radio users to wait for a specific
frequency to clear before transmitting. Trunked systems allow more groups of 2-way radio users to use
fewer frequencies. Instead of selecting a specific frequency to transmit on, a trunked system chooses one
of several frequencies when the 2-way radio user transmits. The system automatically transmits the call on
that frequency, and also sends a code that identifies that 2-way radio user’s transmission on a control
