To use the product normally, it is sufficient to switch the headphones on and off exclusively by using button "A" (press
for 3 seconds to switch on, press for 5 seconds to switch off)
When the headphones are not in use, it is advisable to switch them off, to avoid completely draining the battery, then
place them correctly on the base (see the paragraph "Charging the batteries"), so that the battery will be charged the
next time you use them.
In the absence of an incoming audio signal, the charging dock automatically switches off after around 5 minutes (the
green indicator light "I" goes out).
If the headphones are not being used for a long period of time, it is advisable to disconnect the AC power adapter from
the power outlet.
Position the headphones (receiver) on the recharge contacts of the base (transmitter) to recharge the internal battery;
N.B.: the headphones may be placed on the base facing in any direction.
The red "I" (POWER/CHARGE) LED light will come on to confirm the headphones are correctly positioned on the base;
the light will switch off when the headphones are fully charged.
The initial charge will take at least 4-5 hours.
Another audio device with an optical digital input (for example another transmitter base or a soundbar) can be connected
to the base of the HP Digital. This device will also be serially connected, together with the HP Digital, to the main audio
source (e.g. the TV). This may be useful if the TV has a single optical input and you wish to reproduce sound through
the HP Digital and from another device.
To allow the audio signal to also reach the other device, connect it to the "O" (OPTICAL OUT) output on the base of the
HP Digital, using a second optical digital audio cable (as shown in figure 5).
