Ocean Technology Systems RCS-15 Operation Instructions

The RCS-15 and RCS-16 smart chargers are universal-

input, nickel-metal hydride (NiMH) battery chargers for 

rapid charging of the RB-11 NiMH batteries used in various 

Ocean Technology Systems (OTS) communications 

products, such as the Aquacom

®

 SSB series of diver 

transceivers and the MK-7 BuddyLine intercom. By 

following the simple instructions provided here, you should 

experience long-term, trouble-free use of your RCS-15 or 

RCS-16 charger.

The RCS-15 and RCS-16 chargers consist of the charging 

module and power output cord as one unit (Fig. 1). The 

power output connector is a 4-pin “Amp” connector; 

additionally, with the RCS-16 is provided a battery snap 

adapter (Page 2, Fig. 2) for direct charging of the battery 

(required for the MK-7 and optional for the SSB-2010, 

SSB-1001B, etc.). A  power input cord is provided with 

your choice of plugs depending on the region of the world 

where the charger is used.

OPERATION                                                          

1.  Connect the power input plug (Fig. 1) to the AC source and the power input connector to the charging module.

2. To charge the RB-11 battery through the communications unit (not applicable to the MK-7), connect the Amp 

power output connector to the communications unit (described in greater detail on back of this page). 

    To charge the battery directly (RCS-16 only), connect the battery snap adapter to the power output connector  

and its battery snap to the RB-11 battery.

3.  Once the connections are made, the charger will 

determine the battery condition before starting to charge 

the battery. The LED on the charging module indicates 

the charging status (Table 1). If the battery is defective or 

damaged, and the LED does not change from GREEN 

to RED after repeated charging attempts, the battery 

may need replacement. (Replacement RB-11 batteries 

are available from OTS or your local dealer.)

4.  When  the  LED  indicates  “trickle  charge”  status  (Table                                

1), charging is complete. Unplug the charger. 

IMPORTANT SAFETY NOTES                                              

1.   Do not attempt to charge alkaline or other non-rechargeable  batteries. Doing so may damage the 

      batteries and/or the charger.

2.   Keep the charger away from water and dust. 

3.   The charger should remain uncovered and properly ventilated while in use.

4.   Use the charger only with the batteries for which it was intended.

If you have any questions about the batteries with which the RCS-15 or RCS-16 should be used, contact Ocean 

Technology Systems.
