AmpliVox VHF S1600 - Manual (Page 4)

POWER SOURCE
The transmitter and receiver are each operated by a 9V alkaline
battery. Before use, install a battery as shown. Make certain the
battery is fully seated in its compartment so the cover slides in place
easily. Battery life with alkaline batteries is approximately 8 hours of
operating time. The receiver also features an external jack for
connecting a 9V DC power supply (not included).
