CHARGING THE FRV BATTERY:
The FRV is equipped with a powerful battery capable of driving the
unit for more than 30, 8-hour days. The level-of-battery-charge screen alternates between “Batt” and
the charge percentage. To charge the unit, use a quarter to remove the charge port screw. Connect
the battery charger provided with this unit where the battery charger green light turns red. A fully dis-
charged battery will take 4- 8-hours to charge. When the battery is fully charged, the light on the wall
charger will change from red to green. The charger will shut off automatically when the battery is full.
Be sure to replace the charge plug or the unit will flood. Take care not to strip the threads. Removing
the charger from the wall socket, but leaving it attached to the actuator drains the battery.
Experts agree that you are properly weighted at the surface when you will not sink even if you fully
exhale. Successful use of the FRV calls for another criteria.
You must not be more than 3 lbs (1-kilo) negative weight at your trigger depth . It is entirely
possible for the diver to overweight and thus defeat the lift values at the trigger depth. Take for
example the diver who dives deep for grouper, who routinely wears 10 kilos (22 lbs) of weights to
be neutral at 2 meters (6 feet) and who is also wearing a 7-mm wetsuit. Suppose he sets his trigger
depth to 41 meters (135 feet) and has installed two 38-gram cylinders, which together will provide 8
kilos (18 lbs) of lift at that depth. (See table on page 14. Should the diver descend to 41 meters (135
feet), it is entirely possible that because of the wetsuit compression and his excessive weights, his
combined negative weight will exceed 8 kilos (18 lbs), which will render the FRV useless. For proper
use of the FRV, it is critical that you do not overweight so that you are more than 1 kilo (2.2 lbs)
negative at your trigger depth. In the above example, the diver should remove extra weight and/or
decrease his trigger depth to a level that will support a higher lift value, or use larger cylinders.

REMOVE THE CHARGE
PORT PLUG WITH A
QUARTER TO PREVENT
FLOODING, BE SURE TO
REPLACE THE PLUG.
CONNECT THE CHARGER AND LOOK FOR THE CHARGING LIGHT
(RED) ON THE CHARGER. IT WILL TURN GREEN WHEN FULLY
CHARGED. (Unfortunately, a few have forgotten to replace their
charger plug and ruined their unit when it flooded—DON’T FORGET!)
DO NOT
• Continually charge the battery to 100% when not being used.
• Use the FRV with a battery charge less than 50% in freezing conditions.
• Allow the battery to remain in a fully-discharged state.
• Do not store the battery in very high or low ambient temperatures.
Caution. Be sure and screw the plug back in. If not, the unit will flood and be ruined.
Wrap the charge plug around the charge wire so you don’t forget it.
