Due to the convenience of the user replaceable battery feature, Oceanic recom- mends that batteries be removed during periods of inactivity expected to ex- ceed one week and during air travel that is not conducted during repetitive dive surface intervals.

  • Page 111: Low Battery Condition

    Low Battery Icons appear on display to alert you of the need for a battery change for either the Transmitter (Fig. 107) or Display Module (Fig. 108). Usually, the DataTrans Plus will only activate if there is enough battery power to complete one full day of diving. Remaining battery life may also be short- ened by a sudden change in temperature.

If found, return your DataTrans Plus to an Au- thorized Oceanic Dealer, and DO NOT use it until it has received service. • To remove the o-ring, press the sides with your fingertips to cause it to protrude slightly from the groove of the cap and lift it over the head of the cap.

    Note: For any cause of flooding other than a bad o-ring, return the complete DataTrans Plus for factory service. Fig. 110 - Battery If moisture is found in the battery compartment, it is best to have your Installation DataTrans Plus inspected and cleaned by an Authorized Oceanic Dealer.

    Note: The retainer ring cannot be removed or replaced by the user. TRANSMITTER INSTALLATION INSTRUCTIONS As an integrated unit the DataTrans Plus requires attachment of its Radio Frequency (R/F) transmitter unit to your regulator first stage. CAUTION: Installing the Transmitter improperly to your regu- lator first stage may damage the Transmitter, regulator, or both.

    ® MORE ABOUT FLYING AFTER DIVING In 1990 the Undersea and Hyperbaric Medical Society (UHMS) published a set of guidelines aimed at minimizing the possibility of decompression sickness due to flying too soon after diving. The UHMS suggests* divers using standard air cylinders and exhibiting no symptoms of decompression sickness wait 24 hours after their last dive to fly in aircraft with cabin pressures up to 8,000 feet (2,440 meters).
