SECTION 3. EQUIPMENT SETUP BATTERY CHARGER NOTE: Set up the battery charger and charge all beltpac and/or all-in-one headset batteries while you are setting up the base station.
BASE STATION Antenna and AC Power Connections 1 2 3 90° angle Screw both antennas onto the connectors on the back of the base station. Tighten at 90° angle. Antenna connectors Set up base station where no objects are blocking the line-of-sight from base station to the beltpacs. If base station can not be set up with no objects in line-of-sight between it and the beltpacs, install the antennas away from the base station. See page 17 for remote antenna installation.
Optional Battery Operation of Base Station NOTE: Always plug base station into AC power when it is available. Turn base station off when it is not being used, to conserve battery power. Typical base station battery life when used continuously is as follows: Energizer Lithium BAT850 Rechargeable Battery Duracell Coppertop 1 2 6 hours 3 hours 1 hour If you are using the battery sled, load 6 “AA” batteries into it.
Spectrum Friendly™ Interference Avoidance Interference such as popping sounds may occur when frequencies of a WiFi system, a wireless DMX lighting system or another HME system is in use. This interference may be avoided if these systems can be limited to one portion of the 2.4GHz to 2.48GHz frequency band, and your base station is set to operate in the opposite half of the band as follows: 1 Turn the base station power on. The STATUS window will show “8” for a few seconds.
Multiple Base Stations Up to 20 crewmembers can communicate in the dual-channel mode, 5 per base station, by interconnecting base stations as described below. Audio Connection Connect base stations with the provided interconnect cable, from the BASE OUT connector on one to the BASE IN connector on the other.
Multiple Base Station Initialization Multiple base stations must be “initialized” according to the following instructions, so their frequencies will not cause interference. After initializing each base station, register each beltpac that will be used with that base station (See page 15). Primary/Secondary Base Station Setting Set the BASE switch on each base station as described below, and then configure each base station through the initialization procedure that follows.
4 5 Press the REGISTER button on the primary base station The STATUS window will show a small “o.” Press the REGISTER button on the secondary base station to assign it a number (1, 2 or 3). Wait until the base is initialized (approximately 10 seconds). RECOMMENDED: If only two base stations will be used, set the secondary base station to #2.
Base Station Microphone Gain Adjustment The microphone gain adjustment allows you to adjust the level of your voice as it is transmitted from the headsets plugged into the base station, to the rest of the system. Microphone gain must be adjusted for each base station headset. 1 2 3 4 5 Use a headset that is plugged into the right side of a base station, and locate the MIC GAIN adjustment that is recessed in a hole on the right side of the base station.
BELTPACS Beltpac Registration NOTE: Registration of all-in-one headsets is the same as the beltpac registration described below, except for step 2. If you have more than one base station, you must register each beltpac and/or all-in-one headset to the base station it will be used with. 1 2 3 Turn the base station power on, and beltpac power off. Plug the headset into the beltpac and put the headset on your head. Press the REGISTER button on the base station registration panel.
Beltpac or All-In-One Headset Adjustments Sidetone Adjustment (Beltpac only, not on all-in-one headset) When you speak into the microphone, you can hear sidetone (your own voice) in the beltpac headset. Sidetone can be adjusted as follows: 1 2 Be sure the beltpac power is on. While holding down the “O” button, press the volume-up ▲ or volume-down ▼ button as many times as needed to reach an acceptable level. You do not hear beeps except for maximum or minimum double beep.
OPTIONAL REMOTE ANTENNA INSTALLATION If it is not possible to avoid obstructions that may block signals between the base station and the beltpacs and/or all-in-one headsets, it may be necessary to locate the antennas away from the base station. Remote antenna kits with either 6 foot (1.83 meter) or 30 foot (9.14 meter) cables can be used to mount the antennas wherever necessary to alleviate this problem. To order a remote antenna kit, see optional equipment on page 3.
OPTIONAL AUXILIARY EQUIPMENT CONNECTION Equipment requiring 4-Wire audio interfacing, such as audio/video recorders or hardwired intercoms, can be connected to the 10-pin connector and plugged into the rear panel of the base station. Equipment requiring relay closure, such as a router or mobile radio, can be connected to the 8-pin connector and plugged into rear panel of the base station.
