◆ Appearance & Components
① Display Meter The cross meter display indicates SWR and impedance simultaneously.
② Frequency Counter This 6-digit LED display indicates the frequency to which the CAA-500 is currently set.
③ Freq Range Selector 6 frequency ranges are provided, yielding coverage of 1.8-500 MHz. Fine tuning is
provided by the FREQ knob (see ⑥ below).
④ Battery Case The battery case accepts six "AA" alkaline batteries to power the CAA-500.
⑤ External Power supply An external DC power supply (8-16V, 250 mA minimum) may be connected here, if
internal batteries are not being used. The center-pin is the positive DC terminal. Be sure to observe the proper
polarity.
⑥ FREQ Knob This knob adjusts the operating frequency of the CAA-500, in conjunction with the Freq Range
Selector described in ③ above. Upward rotation of the knob increases the frequency.
⑦ POWER Switch This is the main Power On/Off switch for the CAA-500. When the power comes on, the
power switch and the LED display will become illuminated.
⑧ Gate Time Switch This switch selects between display resolutions of 1 kHz (FAST) and 100 Hz (SLOW).
Above 100 MHz, the left-most digit of the display will not appear, so remember the approximate frequency, or
confirm it by temporarily returning to the FAST mode.
⑨ Output Connector Two output connectors are provided in the CAA-500. When using the "A" through "F"
frequency ranges, use the "M" ("UHF" or "SO-239") connector; when using the "High Range" selection (above
255 MHz), use the "N" connector.
⑩ Hand Strap Attachment point The Hand Strap may be attached here; any suitably-strong strap of at least 1
mm diameter may be utilized.
*Please install the strap with the thickness whose installation string diameter is 1mm or more.
