Monitoring Voltage Input at power jack and Battery Charging
The presence of a voltage greater than (>) 0.3 VDC indicates the presence of the power
source (power supply, battery, etc). Any voltage in the range of 5.0 – 20V is permissible.
When a power source is present, the batteries will be charged with the CTX-10 either
ON
or
OFF
.
The internal micro-processor will prevent transmitting (at any RF power setting), once the
battery charge state has fallen below 20% remaining capacity. Receiver-only operation
can continue down to 10% capacity before an orderly shut-down (with data saved) is
initiated.
???The battery voltage and remaining capacity is shown on the display during RX ???
