Telex PW24 manual Guidelines and recommendations for best performance, Compatibility

4) Guidelines and recommendations for best performance.

Compatibility

The transmitter and receiver must synchronize to work together by placing the transmitter into the charging cradle while on. The In-Use LEDs will flash three times and the two are synchronized. Any PR24 can be synchronized with any PB24 base.

Using Multiple Wireless Systems

The PW24 system has 40 possible “channels” that are really different frequency hopping schemes. Each synchronized base and transmitter will automatically find a clear channel so up to 40 systems can work together in one location depending on other interference problems.

Potential Sources of Interference

There are many potential sources of interference for your wireless system. Any electronic product that contains digital circuitry including digital signal processors (reverb/multi-effects units), electronic keyboards, digital lighting controllers, CD and DVD players, and computers, all emit RF energy that can adversely affect the performance of your wireless system. It is always best to place the receiver as far away as possible from these devices to minimize potential problems.

The PW24 operates in the 2.4MHz ISM band and other devices in that band may interfere. The spread spectrum technique used in the PW24 is very robust and should operate even in the presence of other 2.4MHz devices such as walkie-talkies, LANs, cordless phones, etc. in the area.

Battery Recommendations

The Lithium-Ion battery built into the PB24 transmitter will work at full capacity for over 500 charge cycles. If you notice lower than usual battery life over time, it may be time to replace the cell.
