Set-up
Below are instructions for the set-up and operation of a single
BTR-24 with up to ten TR-24's.
1.
Prior to use the TR-24 and BTR-24 should have their battery
packs fully charged. Refer to the “Battery Charging
Instructions” near the end of this section.
2. Plug the BTR-24's external power supply into an AC outlet if
available. If external power is not available then the unit can
run off internal battery.
3.
Connect the antennas to the BTR-24.
4. Place the BTR-24's antennas in a location where they will
have the best line-of-site to the area of coverage.
NOTE: The BTR-24 system operates in the 2.4 GHz spectrum.
Keep coaxial cables as short as possible to reduce signal loss in
the cable.
5. Power the BTR-24 by turning the power switch to ON.
• The power light should immediately light solid.
• After 20 seconds the base station will clear scan the
spectrum and place the unit on the best RF channel.
• After the scan, the AP Active light will flash, indicating a
successful boot.
• After the boot the user may clear scan again, manually set
a RF channel or lock a channel. See section 2, “BTR-24
Controls and Connection”, for details.
6. Plug headsets into the TR-24 beltpacks.
7. When the BTR-24 has finished booting, power-up the TR-24
beltpacks in wireless mode. The wireless mode is entered by
holding the <TALK> button down as the unit boots. Once a
beltpack was booted in a mode (wireless, wired, master
wireless), the beltpack will always boot in that mode until the
user sets a different boot mode.
• The power light should immediately light solid.
• After 20 seconds a beltpack voice prompt will announce
“wireless” in the headphone.
• Audio channel one’s light will activate indicating
communication has started.
System Operation
By following the previous setup instruction, the system should
now be up and running. Please read the following information for
optimization / best performance of that system.
Beltpack position - When operating the system, wear the
beltpack on the hip. Place it in a position that allows for greatest
visibility to the BTR-24 antennas. The internal antennas for the
TR-24 are on the sides of the beltpack case. For best visibility of
antennas, do not place other objects within 6 inches (15cm) of the
beltpack on the belt.
