TROUbLEShOOTING
We offer this section so that you may evaluate and possibly correct any
problem you may have with your PRO EARS before contacting customer
service. If it becomes necessary to return anything for service, please call our
Service Department at 800-891-3660 to obtain an RMA (Return Merchandise
Authorization) before shipping.
1. No Sound – Check the batteries. While we actually receive a low number of
Warranty returns, over half of the units returned are battery related. Please
make sure the batteries are the correct ‘N’ Size, 1.5 volt (or Lithium 123a for
certain Pro Tac Gold models) are in good working order, and are facing in the
proper direction. The spring end in the battery box is the negative end of the
battery (as marked in the battery box). Many of the battery problems occur
when using the wrong batteries. There is a similar sized, 12 volt battery on
the market that is the same length with a slightly smaller diameter. Using the
wrong model battery will void your warranty. Use only the ‘N’ size, 1.5 volt
battery (or Lithium 123a for certain Pro Tac Gold models).
2. Sound is intermittent – Batteries are weak or not properly seated in the
battery holder. Replace the batteries.
3. Sound is not clear or is distorted – Batteries are weak. Replace the batteries.
4. Hear a beeping sound – (Gold models only) This is the low battery warning
signal. See Audible Battery Life Indicator in the Operation Section of this manual.
5. Sound when using the MP3 player is “clipped” – Make sure the Jumpers
have not become dislodged and are set to MP3. All PRO EARS Gold electronic
models use jumpers on the circuit board to allow you to customize the sound
from an external source. To make sure the Jumpers have not become
dislodged, open the foam battery flap in the ear cup and inspect the Jumpers.
The Jumpers are located below the battery box. Make sure a Jumper is
covering both the pins marked Radio or MP3 as desired.
6. Insufficient Amplification or Gain – Check the Jumper settings. All PRO
EARS Gold Series models have a special, internal set of Connector Pins or
Jumpers that are used to alter the circuit board Gain settings. These Jumpers
are independent of the volume controls. The internal sensitivity is set at the
factory to a low for the Gold Series.
7. Noise attenuation has decreased – The cups need to fit securely around
your ear to obtain maximum noise attenuation. The ear seal material used in
all PRO EARS is designed for maximum comfort and effectiveness. Like a set
of high speed tires on a racing car, these high performance ear seals need to
be replaced periodically to maintain their effectiveness. If the ear seal feels
rough or is cracked, replace immediately. Hair or eye glasses can create a gap
between the ear seal and the head. The ear seal is designed to limit the impact
of wearing glasses but cannot eliminate the gap. Try wearing a glasses with
thinner or flatter stems. Good headband compression is also necessary for
a proper fit. Our headbands are designed to provide sufficient compression
to be effective but not too much compression to cause headaches. Over time
the headband can stretch out and may need to be replaced.
