For your safety 19
Unapproved modifications or changes
to radio
The radio is designed to satisfy the applicable compliance
regulations. Do not make modifications or changes to the
radio that are not expressly approved by Tait. Failure to
do so could invalidate compliance requirements and void
the user’s authority to operate the radio.
Engraving and modification of intrinsically safe
radios
Warning Intrinsically Safe (IS) radios and batteries must
not be engraved or modified in any way. For more
information on IS radios refer to
"Intrinsically Safe
radios" on page 16 .
Engraving a magnesium chassis will void
warranty
Notice Engraving the magnesium chassis of an older
radio can significantly reduce its mechanical strength and
will void any warranty. The magnesium chassis is metallic
black and painted. The aluminium chassis of newer radios
is silver gray and unpainted. If a magnesium chassis has
been engraved, it must be replaced.
Attaching of labels
Warning Do not obstruct the vent hole on the battery. If
the vent on the battery is obstructed, the battery may
explode, causing personal injury and/or damage to
property.
Caution Tait recommends that you do not affix additional
labels to the surfaces between the radio chassis and the
battery. The fit between these surfaces is intentionally firm
and any added thickness will damage the points of
attachment between radio and battery. If you must attach
a customized label, use only a thin gummed paper label
applied to the bottom 25% of the radio chassis label and/
or to the top 25% of the battery label. Do not obstruct the
vent holes (see Warning above). Do not allow the paper
label to extend beyond the recessed label area or to
conceal relevant product information.
