USE EARBUDS (ILLUSTRATION E)

After opening the charging box, the illuminated rings on the earbuds indicate the charging status.
The earbuds switch on automatically when they are removed from the charging box. When placed in the charging box, the earbuds automatically switch oﬀ again. The earbuds switch oﬀ after 30 minutes of non-use when they are not in the charging box.
If the earbuds are under Jobsite Aware Mode mode, the earbuds will not be switched oﬀ. Only at the status of the Bluetooth connection, the earbuds will switch oﬀ .
When the Earbuds are taken out of the charging box for the ﬁ rst time, they switch on and go into pairing mode (the light rings ﬂash blue). On the device (mobile phone, tablet…) that is to be connected,
open the Bluetooth settings and establish the connection with “REDLITHIUM USB Jobsite Earbuds”. The connection is displayed and the battery capacity of the Earbuds is indicated.
The Earbuds remain connected to the device as long as they are switched on and within range. When the Earbuds are switched oﬀ (e.g. placed in the charging box), the Bluetooth connection is disconnected. When switched on, the Bluetooth connection is automatically re-established.
If the Bluetooth connection is not established automatically (e.g. because the device was manually disconnected), the Bluetooth connection can be
re-established manually. To do this, manually turn oﬀ the earbuds, press the buttons on both Earbuds for 3 seconds – the switch-on signal sounds. Then press and hold both buttons for a further 5 seconds – a 3-chime tone will sound when earbuds activate pairing mode.
The earbuds will continue to search for a signal for 3 minutes.

JOBSITE AWARE MODE
This is a microphone technology that allows the user to hear the world around them, but always at a safe listening level. When ambient noise breaches a safe listening level, the microphone technology immediately responds and attenuates to a safe level.

INSTALLING EARRINGS (ILLUSTRATION D)

The earwings can provide a better hold in the ears. This depends on the anatomy of the user. Make sure the earwings ﬁt correctly (see illustration).

INSTALLING INSERTS
Inserts in diﬀ erent sizes are supplied. The inserts are simply clipped on. Spare inserts can be stored in the charging box.
Decide which inserts you want to use:
Silicone inserts: comfortable but less sound absorption.
Foam inserts: better sound absorption.

INSERT EAR-PLUGS (SECTION E)

Wash hands before use.

If using foam inserts gently roll the insert between thumb and ﬁ ngers, slowly increasing pressure until earplug is compressed into a thin, smooth cylinder.
To insert the earplug pull the outer ear up and back with one hand and insert the earplug into the ear canal with the other hand.
If using foam inserts hold the earplug in place for at least 40 seconds, allowing the ear plug to expand down into the ear canal.
If using earwings turn the Earbuds until the Earbuds ﬁ ts.
Make accoustical check: once both Earbuds are properly in place, listen to a loud, steady sound. Cover ears with a cupped hand – the sound should not change signiﬁcantly. If you cannot obtain a good ﬁt, try a diﬀerent type of hearing protector.
Start music on the device or make a call.
Removal: Remove Earbuds slowly with a twisting motion.
Wear the Earbuds for as long as the exposure to the noise persist.
Re-check the ﬁ t often. The Earbuds could loosen up when you talk and chew. This could lose your noise protection.
