POWER SUPPLY
• VTX Battery >> (1) 3 vdc, CR2, Lithium, 800 mAh - Duracell, Energizer, Panasonic, or RayOvac recommended.
• Use life (examples) >> 15 hours at 100% Brightness with Auto Dim set OFF; 34 hours at 60% Brightness with Auto Dim To
time set for 10 seconds and Dim level set for 10%. Refer to page 62 for more information relating to power usage.
Once a low battery alarm condition occurs (red icon flashing), sufficient time should be available to
ascend to the surface while Brightness is held to 60% maximum.
• Transmitter Battery (each) >> (1) 3 vdc, CR2, 800 mAh, Lithium.
• Use life >> 300 dive hours if (2) 1 hour dives per dive day.
• Replacement >> by user (annual recommended).
POWER SAVER MODE (PSM)
When 2 minutes elapse without any button being pressed while on the surface, the unit will enter a Power Saver Mode (PSM)
which turns the display screen off until a button is pressed at which time it will turn back on.
During the time that the screen is off, operations continue as normal in the background with current updated information dis-
played after the screen comes on again.
An Auto Dim feature can also be used to save power during dives by dimming the display screen to a % level of Brightness that
you set prior to the dives. Oceanic recommends that you take advantage of this feature. Refer to pages 13 and 62.
BATTERY STATUS
To access, while viewing the Home Menu when on the surface >>
• S (< 2 sec) to access Home Setup Menu, then -
• A or M (< 2 sec) until BATT, TMT STATUS is highlighted (Fig. 5).
• S (< 2 sec) then activates the unit's receiver displaying a Please Wait message (Fig. 6A) for 3 seconds, then the Status
screen appears (Fig. 6B).
A color coded Low Battery icon is displayed at the lower/left of Surface and Dive Main screens when battery power is low.
• No icon = means battery power is good and you have sufficient power to conduct normal diving activities.
• Yellow = caution (warning), meaning you should have sufficient battery power to complete a normal 1 hour dive.
• Red (while on the surface) = alarm, meaning the battery must be changed prior to starting a dive.
• Red (during a dive) = alarm, meaning you should savely ascend to the surface and replace the battery before continuing
with diving activities. Caution - The unit may shut off at any time without further warning.
LOW BATTERY WARNING
• The Battery icon will be displayed (yellow) when voltage decreases to 2.75 vdc.
• Battery change prior to any diving is recommended. Less than 1 hour dive time may be expected.
• The graphics LOW BATTERY will alternate with NORM (or GAUG or FREE) on the Surface Main (Fig. 7).
• If a dive is started, the graphic is not displayed on the dive mode screens.
• Brightness level will be limited to 60% with other functions continuing as usual.
LOW BATTERY ALARM
• The Battery icon will change from yellow to red (flashing) when voltage decreases to 2.50 vdc.
• Entry into dive modes and compass use is blocked. Battery change is required prior to starting any dives.
• The graphics CHANGE BATTERY (red) will flash on the Surface Main (Fig. 8A) until the battery is changed or the unit shuts
off due to voltage being too low to sustane operations.
• If a dive is in progress, the red Battery icon will flash and the graphics GO UP LOW BATTERY (red) will be displayed with 2
red Up Arrows (Fig. 8B) that will alternate with the usual information displayed until on the surface.
Ascent should be made to the surface following proper ascent protocols, respecting ascent speeds
allowed, and Deco and Safety Stops if possible.
TRANSMITTER (TMT) BATTERY STATUS
Indication is provided only while on the surface.
Low Battery Warning
• The graphics BATT LOW appear solid (yellow) on the Status screen (see Fig. 6B).
• DC functions continue to be available (surface and dive).
Low Battery Alarm
• The graphics TMTx LOW BATTERY (red) alternate with the graphics NORM (or GAUG) on the SURF Main screen (Fig. 9).
• The graphics BATT LOW (red) also flash on the Status screen.
• TMT operation continues until Tank Pressure decreases to 50 PSI at which time the TMT's link is lost.
