Quick Start Guide HM ELECTRONICS, INC. 2848 Whiptail Loop, Carlsbad, CA 92010 USA Phone: 1-800-848-4468 Fax: 858-552-0172 Website: www.hme.com Email: [email protected] HME# PUB - 000xx Rev A 10/26/20 AC70 BATTERY CHARGER The AC70 Battery Charger can charge up to four BAT70 lithium-ion batteries at the same time. LEDs at the charging ports indicate bat- tery status. Charge time is two hours. The AC70 can be used on a desktop or mounted on a wall. TOOLS/EQUIPMENT REQUIRED (for wall mounting only) •Drill and drill bits (~ 3 /16 th inch (4.76 mm)) •Screwdriver (Phillips #2) •Safety Glasses INSTALLATION AND SETUP Note: The AC70 is wireless and requires close physical proximity to communicate with the Base Station/Remote Transceiver. Desktop instructions: 1.Place the AC70 on a level desktop or shelf. 2.Connect the power adapter to a wall outlet, and the other end to the power connector on the AC70 (Fig. 1). Wall mount instructions: 1.Drill two holes two inches apart along a vertical axis on the wall (avoid electrical or plumbing obstructions). 2.Install the provided hardware but do not tighten, leave a gap (~ ¹/8 th inch (3.2 mm)) between the screw heads and wall. 3.Align the AC70 mounting holes with the two screws (Fig. 2). 4.Mount the AC70 over the screw heads until flush against the wall, then slide it down onto the screws to secure it in place. OPERATION 1.Connect the power adapter to a wall outlet, and the other end to the power connector on the AC70 (Fig. 1). 2.Position the BAT70 battery correctly for insertion into the AC70. 3.Insert the BAT70 battery into a vacant port to begin charging. LED activity indicates battery status (see table below).
