BATTERY REPLACEMENT

   Performance may deteriorate with battery usage. The typical period of continuous use that can be expected from the hearing protector batteries is 200 hours. When the output level of the hearing protector is no longer satisfactory, the batteries should be replaced. Ear-tect Model ET-E1 uses 4 (LR03) AAA alkaline batteries (not supplied). Replace the batteries as follows: Insert a large flat bladed screwdriver into the slot between the cup and the cushion (in the position shown) and gently twist the screwdriver to lever off the cushion. Insert 2 x AAA batteries into the holders in each cup, being careful to ensure the polarity is correct. Then replace the foam and the cushion and push the cushion firmly onto the cup. Check that it has ‘clicked’ home all around the edge. CAUTION! If the batteries are inserted the wrong way round and the hearing protectors are “switched on” the batteries will quickly deteriorate, but no harm will come to hearing protector’s circuit.

 

CLEANING

   The ear-muffs should be cleaned and disinfected at regular intervals, using soap and water or a mild disinfectant that is safe for skin contact, and will not adversely affect ABS or PVC plastics. Ensure that liquid does not enter cup. This product may be adversely affected by certain chemical substances, please only ensure use of cleaning agents that will not cause damage to the plastic or foam components.
