[. . . ] A lightning symbol will be displayed every time the SOLUTION ALFA receives a valid signal. 50 WARNING: In case there are several divers using SOLUTION ALFAs with wireless transmission always ensure that all divers are on different codes before starting the dive. The user can manually change the transmitters code by reducing the pressure to less than 10 bar [145 psi] and then immediately (within 10-12s) increasing the pressure above 15 bar [220 psi]. NOTE: In order to save battery energy the transmitter shuts off if the pressure remains unchanged for more than 5 minutes and it will continue transmitting with the saved code when any pressure change is measured. 5. 3. 3. TRANSMISSION DATA After the pairing procedure the SOLUTION ALFA will receive cylinder pressure data from the transmitter. The pressure is displayed in either bars or psi depending on the unit selection. Any time the SOLUTION ALFA receives an appropriate signal it flashes the lightning figure in the display's lower left corner. A pressure reading of over 360 bar [5220 psi] will display as "---" (Fig. If the SOLUTION ALFA is unable to receive a valid signal for more than one minute it will start displaying "FAIL" intermittently with the latest valid pressure reading (Fig. In case the transmitter battery is running low, a low battery warning "LOBT" will be transmitted and displayed intermittently with the pressure reading on the SOLUTION ALFA (Fig. 5. 30 d). 51 If the dive is started without that the SOLUTION ALFA and the transmitter have been properly paired, the SOLUTION ALFA will indicate that no cylinder data is available by displaying "OFF" (Fig. PRESSURE TRANSMISSION RELATED DISPLAYS Display Cd:---FAIL Indication Set Code. After 30 - 60 seconds (sometimes more, depending on your air consumption), the first estimation of remaining air time will be shown in the left center window of the display. The calculation is always based on the actual pressure drop in your cylinder and will automatically adapt to your cylinder size and current air consumption. The change in your air consumption will be based on constant one second interval pressure measurements over 30 - 60 second periods. An increase in air consumption will influence the remaining air time rapidly, while a drop in air consumption will increase the air time slowly. Thus a too optimistic air time estimation, caused by a temporary drop in air consumption, is avoided. 56 The remaining air time calculation includes a 35 bar [500 psi] safety reserve. This means that when the instrument shows the air time to be zero, there is still about 35 bar [500 psi] pressure left in your cylinder depending on your air consumption rate. With a high consumption rate the limit will be close to 50 bar [725 psi] and with a low rate close to 35 bar [500 psi]. Filling your BC will affect the air time calculation, due to the temporary increase in air consumption. A change of temperature will affect the cylinder pressure and consequently the air time calculation. Low Air Pressure Warnings The dive computer will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar [725 psi] (Fig. Three double beeps are also heard when the cylinder pressure goes down to the user selected alarm pressure and when the remaining air time reaches zero.
