lor much langer. Indeed, lor this reason we also recommend their
use on the 10 mW transmitter (SK 1010-6). IIan accumulator is used
instead 01dry batteries - Le. regular use 01the transmitter leads to
Irequent changing batteries- then the accumulator (e.g.Tr 7/8)
can be easily charged using the automatic charger SZL 1010 (Iig. 6).
Changing the antenna
II any delect occurs, the antenna may be unscrewed through the
slot @ with a small screwdriver.
II the SK
1010is to be used as an hand-held microphone, it is pos-
sible to exchange the long wire antenna by a shorter helical
antenna. This helical antenna is available in the lollowing versions:
A 4 (32-38 MHz)
Antenna
lor SK 1010-6 and SK 1010-7,
Irequency range: 32 - 38 MHz
A 4 (38-45 MHz)
Antenna
lor SK 1010-6 and SK 1010-7,
Irequency range: 38-45 MHz
A 3 (138-260 MHz)
Antenna lor SK1010-9,
Irequency range:138-260 MHz
When ordering please state the exact transmitting Irequency.
Direct your order to your next Sennheiser distributor.
Tips for use
For good high-Irequency radiation It is important to ensure that wire
antenna 0 (Iig. 1) hangs downwards as Ireely as possible. When
using microphones wh ich are to be connected via a cable, the
transmitter and therelore also the antenna should be positioned as
high as possible.
