If you detect an unusual vibration or noise in the operation of your Sonet, try to determine the cause. Be sure
the power is off before investigating. If you cannot discover the cause of a problem contact your Sonet dealer or
TGA for help.
Airline Checking
Sealed Lead Acid Batteries are permitted on aeroplanes. A sticker on the battery case states what they are.
Airline personnel may insist on removing the battery cover to verity its contents. It is best to check with the
airline before hand. An airline compliance certificate is available from TGA.
Storage
Avoid storing your Sonet in locations with extreme heat or cold. A cool dry location is ideal if possible. The
following steps will help keep rust and corrosion from impairing your Sonet’s function and appearance. Turn the
key to the off position. Clean all exterior surfaces, touch-up any damaged paint. Check and inflate the tyres to
35 PSI. Be sure the battery is fully charged before prolonged periods of storage and be sure to recharge every 6
weeks. Failure to comply may result in battery replacement.
Batteries
Keeping your Sonet working to its maximum potential means that it’s two batteries must be maintained with full
power. Nightly recharging, after use, will help you to give them a longer life and will ensure your Sonet is always
ready to go when you are. However, occasionally running the batteries down as far as safely possible is also a
good idea as it allows the batteries to then take a full charge.
Your Sonet is fitted with two sealed maintenance free batteries, especially designed for powered mobility. This
means that you do not have to worry about topping up the cells.
Care! Warning
Do not attempt to remove the safety valves located on top of the battery. Failure to observe this warning will
void your battery warranty.
Your Sonet batteries are maintenance free because the electrolyte is immobilised in a special form and will not
leak out, even if the batteries overturn.
10. Battery Charging
The battery charger supplied is special to your Sonet and so it may not be suitable for any other powered
mobility product. Only use the charger supplied with your Sonet as other makes of chargers may permanently
damage your batteries and would void the warranty.
To charge your batteries follow these simple steps.
1. Switch OFF your Sonet and remove the key.
2. Plug the charger lead into the socket located at the rear of the handlebar console (Fig 5.2).
3. Push the plug from the charger into a suitable wall outlet and switch on.
4. You will see 2 lights on the front of the charger.
The green light will be indicating mains on and the other one will be amber indicating that the batteries
are charging. When the amber light changes to green, the batteries are fully charged.
5. When the batteries reach their charged state, the charger will automatically stop charging. The lights
will, however, still be on but the batteries cannot overcharge.
6. Although to get out of trouble the batteries can be put on charge for a short period of time, it is always
best to go through a complete charge cycle each time. Excessive short period charging will be
detrimental to battery life.
7. For the best results and to prolong battery life, try to run the battery down by at least 50% before
recharging and in addition it is always best to go through a complete charge cycle each time.
8. Depending on the depth of the discharge, the minimum time taken to recharge serviceable batteries fully
will vary up to 12 hours. Please note that this time may increase as batteries get older. During periods
without use (perhaps during the winter) it is wise to charge the batteries every 4 to 6 weeks.
