Section 5 Initial Equipment Set-Up Unpacking Unpack your Clear-Com System. Below are the items that should come with your base station and each belt pack.
Antenna Connection The base station is supplied with two (2) antennas. One 1/2-wave antenna for Transmit and one 1/2-wave for Receive. The antennas have TNC male connectors.
Keep the distance between the base station and the beltpacks as short as possible. The greater the distance, the weaker the signal. Make sure the “signal paths” between the base station and beltpacks are unobstructed. You should be able to visibly locate the base station antennas at all times for best performance. Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. will reduce system range and performance.
2. Placing the WBS's on top of a shelf or equipment rack un ob structe d with out remoting the an ten nas is OK. 3. Placing WBS's in a shelf or equipment rack with the antennas mounted on the back of the WBS or the side of the rack is BAD. 1. Placing WBS's in a shelf or equipment rack and using remote antennas is OK.

Internal Transmit Switches Intercom Switch Internal to the WBS-680 are two transmit switches which enable a user to turn on or off the two transmitters individually. See Figure 19 for the location. The top cover of the base station must be removed for access. The switch closest to the front panel controls transmitter 1 (audio channel A). The switch behind that is transmitter 2 (audio channel B). The default switch position is to the left if you are facing the front of the base station.
Dual Listen Functionality They will also have the ability to control the level of the mix (-4 dB to -24 dB down from main channel). Removing two surface mount resistors and installing two SPDT switches and two potentiometer enables dual listen. The parts to be installed are shown in Table 1. The two resistors on the board to be removed are in Table 2. The base station’s main audio board has the option of placing additional parts to enable dual listen. Dual listen allows the mixing of the intercom channels.
Auxiliary Input/Output The output auxiliary audio is also taken from the intercom B base local headset, beltpack(s), headsets, and any wired intercom connected to the base station. A modification document is available from Clear-Com for those who wish to modify the base station so that auxiliary input audio is heard only locally; base local headset and beltpack(s) headsets.

Section 6 Pre-Walk-Thru Checklist Following the instructions fully to this point you have successfully completed the following checklist: ❒ ❒ ❒ ❒ ❒ ❒ ❒ ❒ Located the base station properly. Connected power to base station. ❒ Connected the 1/2-wave antennas to the base station. Checked frequency range of the antennas with the frequency of the base station by correctly matching color codes. ❒ ❒ Connected 1/4-wave antenna to the beltpack.

Section 7 System Operation Frequency Plan Overview System Quick Start The WBS/WTR-680 has 36 factory-defined frequency groups and 12 user-programmable frequency groups. A Group defines the two base-station transmit frequencies and thus the two receive frequencies on all the beltpacks. A Channel defines a base-station receive frequency and thus a beltpack transmit frequency.

Section 9 Troubleshooting Reread the sections of this manual to make sure you have completed system set-up properly. If you are unable to solve the problem, contact the dealer from whom you purchased the system for assistance. PROBLEM SOLUTION DISTORTION - System’s audio quality seems distorted at medium to high input levels. Reduce microphone gain by adjusting microphone gain control. HISS - System seems to produce a “hiss” which is undesirable. Check the gain setting on all beltpacks and the base.

Section 10 Tech Tips Frequency Interaction Unfortunately, radio frequency (RF) channels cannot be randomly selected for use in radio devices. They must be selected to avoid known frequencies in use, FCC restrictions on the location of devices, and even interference between your own RF devices. The factory defined frequencies (Groups 01A-24) selected for this system are chosen to minimize possible interference.
