Battery Safety
Batteries may leak fluids which can cause chemical burns, toxicity, or ruin your product. To avoid
leakages, take note of the following:
• Remove batteries if the amplifier will not be used in the near future.
• Remove exhausted batteries immediately.
• Do not attempt to recharge non-rechargeable batteries. They may explode.
• Do not mix old and new batteries.
• Do not dispose of batteries (or this product) in a fire. The batteries
may explode.
• Batteries must be inserted with the correct polarity!
The A10L amplifier uses two 1.5 volt “AA” batteries. Alkaline “AA” batteries will provide best
performance and battery life, but standard (carbon-zinc) batteries may be used if alkaline types
are not available.
Rechargeable batteries are NOT recommended for use in the A10L amplifier, due to their lower
voltage.
Hearing Protection
Do not listen at extremely high volume levels. Extended high volume listening can lead to
permanent hearing loss!
The ADDCOM A10L amplifier is designed to limit the audio output to a level which will not induce
acoustic shock (i.e. transient, painful noises such as clicks, crackles or malicious whistling).
The ADDCOM A10L amplifier cannot protect from acoustic fatigue, as it is a progressive condition
which results from long-term exposure to high sound levels. Many countries now have regulations
which limit the amount of noise that an individual can be subjected to over the course of a
working day, in order to reduce the incidence of acoustic fatigue.
It is the responsibility of the user to ensure that they listen to their headset at a volume which will
comply with local hearing protection regulations.
A quiet working environment and a snug-fitting headset will allow the user to have good
intelligibility and clarity at the lowest volume settings, minimising the possibility of hearing damage.
