Katsumi ele-key EK-150 Manuals

KATSUMI ELECTRONIC KEYER EK-150 INSTALLATION INSTRUCTION FEATURES The ELE-KEY model EK-150 itself forms the dots, dashes and spaces in the precise ratio required for perfect code, at any speed desired by the operator. Plug-in unit P.C.B. and solid state circuitry. Squeeze (IAMBIC) sending with full dot and dash memories. Built-in sidetone with tone and volume control, switch for SEMI(BUG)/AUTO. Built-in speaker, headphone jack. Heavy duty transistor switch (2SB546) for 150 V, 2 Amp. DC and with a built-in high speed plate relay for max. 700 V, 500 mA any transmitter keying. Operation on 100 to 120 V/50 – 60 Hz or DC 7 – 13.5 V. Respectively Operation on 220 to 240 V/50 – 60 Hz or DC 7 – 13.5 V. OPERATION (1) Check polarity and the required keying voltage and current on your transmitter key terminals, using a tester (voltmeter, milliameter) the key up (open circuit) voltage must not be in excess of .50 volts D.C. (2) Connect the key line (output) [11] on the rear panel terminal (+) to the POSITIVE keying terminal of the transmitter, and the (–) to the NEGATIVE terminal, as previously determined by voltmeter test (1). (3) Plug in the power cord [14] to the 100 to 120 volts resp. 220 to 240 volts, 50 to 60 Hz alternating current supply. Set the power switch [6] to the ON position. The pilot lamp [7] should light. (4) Moving the dual key levers to the dot position (push to the right for [3] left key lever) should result in dots being heard from the speaker and moving the dual key lever to the dash position (push to left for [4] right key lever) should produce dashes.
