Turning on the controller

Left and right buttons
6.5.1 Left
(MENU)
In order to turning on the controller press both buttons at the same time. The JJ-CCR logo
appears for a brief time, following by the controller’s main display.
As previously described, complete operation of the controller is implemented via the two piezo but-
tons. Although both buttons also have special functions, it is possible to summarise the main function
as follows:
The left button (MENU) is used in order
to scroll between the various controller
menus. Or, if it is necessary to set a value,
in order to increase this. In this way, one is
able to press briefly on the left button in
order to move from the ”Switch Setpoint”
menu to the ”Select Gas” menu.
If one is in the ”Select Gas” menu then
pressing briefly on the left button will
switch to the next gas.
•
For divers at high altitudes the surface pressure is determined by the following: When in sleep mode
(off), the pressure is sampled every 10 seconds. The last 10 minutes of pressure samples are saved. Upon
turn-on (regardless of the cause), the minimum pressure from the 10 minute pressure history is set as the
surface pressure. The exception is when the battery is changed, since there is no 10 minute history. In
this case it is assumed tha the unit is on the surface, so current pressure is used as the surface pressure.
•
At the surface the controller turnes off again automatically after 45 minutes.
•
During the first 2 minutes after diving the controller maintains surface interval and it cannot be turned
off at this time.
