EARMUFFS
1. Open battery lid. Insert two AAA batteries. Make
sure poles are in correct position. Ensure battery lid
is closed completely. (See Figure 1)
NOTE: Extend headband before use.
• Place earcups over ears with microphones in
forward position to obtain best listening conditions.
(See Figure 2a)
• Ear cushions should seal firmly against head. For
best results, remove all hair under cushion. Noise
reduction is adversely affected by anything
impairing seal of earmuff cushions against the head,
such as thick spectacle frames, balaclavas, etc.
(See Figure 2b)
• Adjust the headband by moving either side up or
down, modifying side slot height. (See Figures 1 and
2c)
• Turn on the volume control and adjust to preferred
listening level.
• After automatic power-off (four hours), turn the
volume control off, wait five seconds, and turn it on
again to get another four hours of working time.
NOTE: Earmuffs should be folded between uses.
(See Figures 3 and 4)
