4. Operation in battery mode*
Before using QuickPresent air for the first time in battery mode, it must be connected to the mains,
and the battery must be fully charged.
In normal use, a fully charged battery will oer an operating time of about 7 hours at full power.
The discharge time of batteries also depends on whether WLAN stick and 60GHz transmitter are active.
The total charging time is approx. 4 hours.

The multi-colour LOGO backlight is also used as charge status display*, see chapter 2.1.1.
Important recommendations for a long battery life:
• Fully charge the battery before first use.
• Try to avoid permanent charging.
• Due to self-discharge, the battery must be charged every 12 months at the latest.
The battery must not be completely discharged in storage.
• The battery has a lifetime of up to approx. 1000 cycles.
• Operate the battery at room temperature. High temperatures exceeding 40°C
during operation should be avoided.
• To ensure a long battery life, deep discharge should also be avoided.
• If the device is not used for a longer time, it should not be completely charged.
If the device is stored for a longer time, the battery should be half full and stored
at cool temperatures.
• In battery mode, always press the POWER push-button to switch o QuickPresent air
whenever it is not being used.
Note:
As soon as the external power pack is connected, the internal memory for battery charge is reset to 100%.
Therefore, the battery should always be charged until it is full.
If the last charging cycle was too short (e.g. only a few minutes), the battery will be fully discharged
without any warning on the display.
