SECTION 4: BATTERIES
The MK2-DCI Two-Diver Air Intercom can be powered by two 6-volt heavy duty
alkaline batteries, rechargeable 6-volt batteries (Ocean Technology Systems’ model
no. RB-6), or a 12-volt alternate source. To recharge RB-6 batteries, obtain an
RCS-13 universal smart charger from OTS or your local OTS dealer.
The following are options for the desired power source:
1) LANTERN BATTERIES: The MK2-DCI is designed to use two 6-volt spring-
connector–type batteries. We recommend the use of 6-volt alkaline batteries,
to achieve optimum performance. Eveready or Duracell alkaline batteries pro-
vide the best results for most diving operations. You can use standard 6-volt
lantern batteries with spring connectors as well; however, battery life will be
greatly reduced, and you will notice a substantial power drop when transmit-
ting.
INSTALLATION OF 6-VOLT BATTERIES: Locate and loosen the four screws
located on the front panel (Fig. 1, #19). These screws are captive and will not
come off the front panel. Remove front panel from housing. Remove cotter pin
from battery strap (Fig. 4, #3). Remove battery strap from battery housing
(Fig. 4, #2). Insert both 6-volt, spring-type lantern batteries, springs facing
toward battery PC board (Fig. 4, #4). Verify that the batteries are secure on the
bottom of the housing and the backs are being held by the back plate. You will
notice the batteries can be installed with springs in any direction on the PC
board (Fig. 5). After batteries are installed, replace the battery strap and cotter
pin, dress the wires so they are not pinched when you put the front panel back
in place, replace the panel, and tighten the four screws (do not overtighten).
2) 6-VOLT RECHARGEABLE BATTERY (RB-6V): When utilizing the optional
RB-6V sealed lead acid battery, you will attain the maximum performance of a
self-contained battery (two are required).
Note: The batteries you receive may have upgraded specifications from what
is stated in this manual. Due to advancing battery technologies, we continu-
ally upgrade our batteries and chargers. Contact OTS or your OTS dealer to
find out the latest available battery and charger.
Install the RB-6V batteries per the instructions found on page 9, “INSTALLA-
TION OF 6-VOLT BATTERIES.”
The RCS-13 universal smart charger is available for rapid charging of RB-6
rechargeable batteries. It closely monitors the batteries’ voltage level to charge
them only as necessary. Power cords compatible with the electrical outlets of
various regions of the world are available for use with the RCS-13.
