Three (3) Band Base Stations
Identifying a Three (3) Band Unit
Three (3) band base station normally have an 18MHz wide
receive range of 650-668MHz. These three (3) band base
stations are designated by having a “3” in the second digit of the
two digit band code that is on a label on the rear panel of the
unit.
Regulatory Changes and the Three Band
There are two channel map configurations in a three band base
station. One for the US/Canada and one for the rest of the world.
At one time (before October, 2018) there was only one channel
map for a three band unit. but due to regulatory changes in the
US/Canada an additional map was produced and installed in
three band base stations. The result of the FCC incentive auction
in regard to wireless intercom was the following:
• Only 10MHz (653-663MHz) may be used for
wireless intercom in the range 616MHz to
698MHz.
• Three band beltpack transmit power must be
reduced to 20mW EiRP for US and Canadian units.
Since the three band units are made for worldwide customers,
the 18MHz range is the default shipped, therefore a US or
Canadian user must set a base station to the new US channel
map in order for the base’s channel map to match the US three
band beltpack’s channel map. The US three band beltpacks only
have the new US channel map in them.
NOTE: Only Canadian users of the three band base station
needs to change the channel map of the base
station to the US channel map!
Changing Channel Maps
A three band base station may be changed from a normal
channel map to a US channel map and back again with the press
of a couple of buttons. The current channel map setting is
remembered by the unit even if power is removed.
1. At the base station’s main operating screen press and hold
[SET]+[UP] buttons until the switching band text is
displayed.

The three band map the unit is switching to will be
displayed.
2. Release the buttons when switching three band text is
shown.

Unit will reboot and display one of the following channel
map versions on boot:
X30001 = Normal three band channel map
X3U001 = US three band channel map
(where X is the current transmit band of the base station.)
