Battery Installation

Each unit may require one to four batteries.
CAUTION: Always observe the correct battery polarity. The negative contact on the battery is always
connected to the spring contact.
Never use any battery that is missing insulation on its body. If you do, it can cause a short circuit in the
battery compartment, causing damage to the unit.

Battery Life

IMPORTANT: If operating using internal batteries, it is recommended that you use only Lithium or
rechargeable NiMH. Any other battery chemistry including Alkaline and Ultra batteries have a substantially
reduced runtime compared to Lithium or NiMH cells. This is true for all Zaxcom units.

External Power

Some of the units can be powered from an external power source. The external power connection is a 2.5 mm
(0.1") barrel connector. The center pin is positive. The connector for the receiver (761K) is longer than the
connector for the STA100 and IFB100 (760K). The 760K will not work in the receiver.
