Guided Tour - AH1 Headset Transmitter

Samson AirLine
1: Power / Battery LED - This LED flashes once when the AH1 is first turned on and lights steadily red when there is less than 2 hours of battery
power remaining, indicating that the battery needs to be changed.
2: Antenna - This permanently attached flexible antenna should be fully extended during normal operations. See the “Setting Up and Using the
AirLine System” section on page 14 in this manual for more information about antenna positioning.
3: Battery compartment - Insert a standard AAA alkaline battery here, being sure to observe the plus and minus polarity markings shown. We
recommend the Duracell type battery. Although rechargeable Ni-Cad batteries can be used, they do not supply adequate current for more than
four hours. WARNING: Do not insert the battery backwards; doing so can cause severe damage to the AH1 and will void your warranty.
