You can listen to your Ranger receiver with stereo
headphones, earbuds and a range of specialized
listening accessories.
Caution - avoid excessive volume levels. Listeners
with normal hearing sensitivity should use low-output
(attenuated) earphones for prolonged use of Ranger.
The receiver volume control can be locked with the
keypad to prevent unintended volume changes.
If you have telecoil-equipped hearing aids or cochlear
implants, use the neckloop or other optional Ranger
coupling accessories to connect to your device
wirelessly. You may have to select a ‘T’ or ‘MT’ setting
on our personal equipment. Consult with your hearing
professional to select the best listening accessory for
your personal equipment.
Note that when no transmission is detected for 20
minutes, the receiver will turn off automatically to
conserve the battery power.
