CITIZEN MG0000 - Manual (Page 36)

Warning Functions
This watch is equipped with various warning functions for the purpose of avoiding risks and
problems when diving as much as possible.
WARNING
* Do not dive in a manner that activates any of the warning functions. Since the degree of
risk varies according to experience, physical condition and diving conditions, do not
assume that diving is completely safe just because none of the warning functions are
activated. Please use the warning functions as a general indicator of diving safety.
Insufficient Charge Warning
When the watch becomes insufficiently charged, "BATT" flashes in the
lower left corner of the display in all of the sub-modes of the standard
mode. Operation of the following functions is limited while this warning
function is activated.
• The watch does not switch to the dive mode even if the water sensor
gets wet. (The watch automatically switches to the battery charge
indicator display of the system monitor mode when the water sensor
gets wet.)
• None of the alarms sound.
• Data cannot be transferred by infrared communication. (However, data can be transmitted to
a personal computer by USB communication.)
• The EL light is not illuminated.
When this warning function is activated, charge the watch by attaching to the communication
unit as soon as possible. The display will return to normal once the watch is sufficiently
charged.
* None of the dive alarms sound when the insufficient charge warning function is activated during
diving. Although the dive computer will function normally for about 30 minutes after "BATT" starts to
flash, the log data for that dive is not recorded. Promptly begin to ascend it this warning function is
activated during diving.
* If the watch remains insufficiently charged after the insufficient charge warning function has been
activated, it switches to the low power mode after about 2 days. Please note that if the watch
continues to be left uncharged in the low power mode, all functions stop and all watch settings return
to the initial (default) settings.
File Error Warning
When the amount of available memory in flash memory becomes low,
"FILE" flashes in the lower left corner of the display in all of the sub-
modes of the standard mode as well as in the dive mode. The watch
automatically switches to the flash memory status display of the system
monitor mode when the water sensor gets wet while this warning function
is activated. Please note that although it is possible to use the watch for
diving in this state, log data may not be recorded in flash memory during
diving.
The file error warning function is also activated and additional log data is not recorded if the
duration of a single dive exceeds 2 hours or if more than 15 dives are made in a single day. The
file error warning function may also be activated when the water temperature during diving is low.
It may not be possible to receive watch settings by data communication while the file error warning
function is activated.
