NOTE: Prior to use, the TR-24 Beltpacks and BTR-24 Base Station need to have their battery packs fully charged. Refer to battery charge instructions.

Wireless Mode

A base station is providing wireless coverage over the area in which the beltpacks will be used.

1.Rack mount or place the BTR-24 base station near the area of wireless coverage.

2.Plug the base station’s external power supply into an AC outlet if available. If external power is not available, then the base station can run off internal battery (if already charged).

3.Connect the antenna(s) to the base station. The antenna(s) must have good line-of-sight over the area of use.

4.Turn-on the base station. After a 20 second boot time the base will scan the area and select the best RF channel.

5.After the base station has selected a channel, turn on the TR-24 beltpacks.

6.To place the beltpack in “wireless mode”, if not already set, press and hold the <TALK> button as the beltpack boots. Release the <TALK> button once boot finishes. The beltpack will always boot in the last mode it was set to until the user sets a different boot mode.

7.After a 20 second boot time the voice prompt “wireless” will be heard in the headphone and the channel light will activate indicating the unit is up.

8.Wear the beltpacks on the hip. Place them in a position that allows for greatest visibility to the base station’s antenna.

Wired Mode

Beltpacks are directly connected to each other via an Ethernet cable or through a building’s Ethernet infrastructure.

1.Place the beltpack(s) near the Ethernet connection.

2.The beltpacks may be powered with their internal battery (if already charged) or external AC. If external AC is desired, use the charging power supplies that come with the beltpacks for this purpose.

3.Connect the beltpack to the an Ethernet cable via the RJ-45 connector at the beltpack’s “EXT” jack. The Ethernet cable may be T-568A or T-568B cables. A normal or crossover cable may be used. The beltpacks automatically detect and use whichever type is connected.

4.To place the beltpack in “wired mode”, if not already set, press and hold the <TWO> button as the beltpack boots. Release the button once boot finishes. The beltpack will always boot in the last mode it was set to until the user sets a different boot mode.

Master Wireless Mode

The base station is eliminated by having a beltpack act as a base station. This “master” beltpack may still be used for audio just as a normal beltpack.

1.The “master wireless mode” is normally a mobile application and as such power is usually supplied by the internal battery (if already charged). However, any beltpack may also run off the charging power supply via an AC outlet if desired.

2.Place a beltpack in “master wireless mode” by pressing and holding the <ONE> button as the beltpack boots. The beltpack always boots in the last mode it was set to until the user sets a different boot mode.

3.After a 20 second boot time the voice prompt “master wireless” will be heard in the headphone and the channel light will activate indicating the unit is up. The button may now be released.

4.After the master beltpack is operating, turn on the other TR-24 beltpack(s). These beltpacks should be booted as in the “wireless mode” instructions since the master beltpack is acting as the base station for the system.

Charging Instructions

1.Plug the external charger into the charge / power jack on the bottom of the beltpack or on the rear of the base station.

2.The LED near the jack indicates the charge status.

•	RED	= Charging
•	GREEN	= Charging Done

Typical Battery Life (from a fully charged battery)

TR-24 = Up to 8 hours
