CAUTION
Be sure to check the keying in your transmitter before connecting the DK-200/DK-210. (Either
GRID BLOCK or DIRECT.) IF your transmitter seems to key continuously, use the other DK-200/DK-
210 keying output. It is best to to verify the keying method used in your transmitter before con-
necting the keyer.
Two transceivers can be connected to the keyer simultaneously . Be sure to use the silicon diode
arrangement for current protection. The total current flowing through the keying output circuitry
must not exceed the maximum current rating of the keyer!
NOTE
For a protection of an RF feed back in the keyer when a station operates with high power output,
it is necessary to use better quality shielded wires for the keying output and/or the key input. All
connecting wires used including the main lead should be connected as shortest as possible.
Operating by a battery
The keyer can be operated by battery (9 Volt). A battery holder is provided inside the cabinet for
connecting a 9-Volt-battery. The battery is cut off whenever the DC plug is connected in the DC
socket. It is recommended to set the side-tone output at low level in order to conserve battery life.
DK-210
It is also suggested to disable the speed indicator LEDs for saving the battery life. The LEDs can
be disabled by cutting the orange-color lead between the PC board of the LED and the LINE
switch.
