Carbon-zinc batteries are the least useful for wireless
microphone operation. Their low cost is more than off-
set by their extremely short operating and shelf life.
Although the “heavy-duty” (HD) carbon-zinc types offer
better low-temperature performance and service capaci-
ty at moderate to high current drain, they will not offer
appreciably better transmitter performance than stan-
dard carbon-zinc batteries.
Although battery operation is inhibited at low
temperatures, storing batteries at low temperatures will
increase their shelf life. They should be sealed in bags
and, when ready for use, allowed to warm up to room
temperature (never heated!). Cold-stored batteries
should be used as soon as possible after bringing up to
room temperature.
Battery life is shortened by storage in high-
temperature locations such as on amplifiers or in
vehicles exposed to direct sunlight.

The battery should be removed if the microphone
malfunctions, or if it is to be stored for a long period.
Most batteries have a protective jacket, but partly or
completely exhausted batteries are more prone to
leakage.
Do not attempt to recharge replaceable (primary) bat-
teries using “chargers”, heat or other methods. This
may cause leakage or explosion. Do not disassemble
batteries or dispose of them in fire.

FCC CERTIFICATION
The Shure Model W15HT/58 microphone is Type-
Accepted under Federal Communications Commission
Parts 90 and 74. Licensing of Shure wireless micro-
phone equipment is the user’s responsibility, and licen-
sability depends on the user’s classification and
application, and on the selected frequency. Shure
strongly urges the user to contact the appropriate
telecommunications authority before choosing and
ordering frequencies other than factory-preset frequen-
cies. This recommendation applies to both original
equipment purchase and subsequent frequency
modification by Shure.
WARRANTY SERVICE
If your Shure wireless microphone equipment should
require servicing under the Shure warranty, please con-
tact:
Shure Brothers Inc.
Attention: Service Department
222 Hartrey Avenue
Evanston, Illinois 60202-3696 U.S.A.
Telephone: (312) 866-5730
All claims of defects or shortage should be directed
to the above address. Please furnish model number,
operating frequency, and date, place and proof of pur-
chase (such as a copy of the sales receipt) to establish
warranty. Your letter should include all pertinent details
including applicable model or part numbers and a brief
description of the problem. Do not return any units or
parts to Shure unless requested to do so by Shure’s Ser-
vice Department. Any returned items must have prior
authorization. Unauthorized returns are delayed in
handling; these delays can be avoided by contacting
Shure in advance and furnishing the necessary informa-
tion.
If you are requested to return the equipment by
Shure’s Service Department, package the unit (with all
information requested) as follows:
Check to see that
all parts are present and in place. If the orginal carton is
not available, place the unit in a strong shipping carton
at least 13 mm (6 in.) larger in all three dimensions than
the unit. Fill the surrounding space with a resilient
packing material such as shredded paper, excelsior,
Styrofoam, etc. Seal and mark the carton in accordance
with postal regulations and ship it prepaid to the Shure
Service Department.
It is extremely important that the packaged unit be
well-packed and fully insured. Damage claims are sub-
ject to settlement between the shipper and the carrier,
and this can delay repair and return of the unit.
Shure reserves the right to make design changes and
product improvements without assuming any obligation
to install these changes or improvements on any pre-
viously manufactured products. Shure also reserves the
right to ship new and/or improved products which are
similar to the form, fit and function of the originally
ordered products.
