Pyramid WM-1000 Product Manual page 13

The WM-1000 is configured to be uniquely paired to one or more WB-1000 base in the vehicle. The WM-
1000 has four channels. These channels can be selected using the mode knob on the WM-1000 handheld
and will select the RF channel and base paired to that channel. This provides private secure communications
to your vehicle mounted mobile radio.
In most cases, WB-1000 is powered from the DB-15 radio connection and requires no external power supply.
There are provisions for external 12V DC on the rear of the WB-1000 for desktop charging/programming.
The WB-1000 is available in a "charge only" version (no RF), model number CH-1000.
The WM-1000 can be configured a couple of different ways, depending on the user requirements. First, if all
your WB-1000 base units are setup identical, having the same RF Band (channel) and RF Address, the WB-
1000 units will operate in a multi-vehicle mode, where they will determine a priority vehicle and all handheld
from WM-1000 units will be passed through the WB-1000 that is priority. This allows handheld users to com-
municate with each other on a common channel (as in a simplex mode) and still have communications with
their dispatch using the priority WB-1000. The WB-1000 base units ESP II structure works to establish one
TM
priority vehicle on the scene to handle traffic to and from the dispatch channel.
Second, you have the option to program each of the WB-1000 base units with a RF Band and RF Address.
This will create a individual pairing from the WM-1000 to the selected WB-1000 and the handheld radios will
not hear each other on the 915 MHz link. They may still be able to communicate with each other through
the mobile radio network, however, the communications between the WM-1000 and that WB-1000 is pri-
vate. There are four different RF Bands to choose from to reduce the chance of RF interference if operating
in this mode.
