18. TROUBLE SHOOTING
Q1 Power is not ON
- Check if the plug is connected to mains
- Check if the power cord is well connected to the pump
- To operate from battery, check if the DC plug is disconnected from the pump unit
Q2 Low Pressure Alarm is on (audible & visual)
- Check if the connection between air tube connector to pump unit is tightly secured
- Check if all tubing connections along cushion are secured
- Check if there is any leakage from air cells
Q3 Cushion becomes too firm and pressure can't be lowered
- The pressure is too firm for too long, release some air by disconnecting the air tube connector
and change to your preferred setting.
Q4 No air is produced from some air outlet of the air tube connector
- This is normal since it is at alternating mode. Air outlets take turns to produce air during their
preset cycle time
Q5 Low Battery Alarm is on (audio & visual)
- Only approx.1 hour of battery power remain, it is a reminder that user must recharge the battery
pack and use AC power source immediately. To mute the alarm, simply press the alarm mute
button.
- After the battery is fully charged (about 5 hours), the pump immediately has 12 hours of
continuous operation time. If it is unable to operate over 12 hours, the battery pack might need
to be replaced.
- If the low battery indicator still lights up after it has been properly recharged for approximately
5 hours, the battery pack might need to be replaced. Replacement required after about 6 months
If the above information does not solve your problems, please contact your local agent directly.
They might require a technician to take care the problem.
