Operating Voltage, Receiving Signals in Cities | Kenwood TH-K2E

OPERATION NOTICES

The transceiver has been designed and engineered to avoid possible hardware glitches. However, you may notice the following symptoms when you operate the transceiver. These symptoms are not malfunctions.

Operating Voltage

As stated in “SPECIFICATIONS” {page 122}, this transceiver operates on 6.0 V ~ 9.0 V DC (battery terminal) or 12.0 V ~ 16.0 V DC (DC IN jack). If you find that the transceiver cannot be switched ON, or “DC ERR” appears, the supplied power source may be outside of the specified range.

In such a case, remove the DC power cable from the transceiver immediately and confirm that the power source voltage is within the specified range.

If you are using a variable DC power supply to operate the transceiver, adjust the DC power supply voltage to

13.8V DC. Considering the output power efficiency and thermal characteristics of the transceiver, this is the optimal voltage to operate the transceiver. If the voltage at DC IN jack exceeds 14.5 V, the transceiver output power is automatically reduced to “” power.

Receiving Signals in Cities

When you receive signals in cities, the receiver’s entire S-meter may light up without receiving any strong signals. This happens when the RF amplifier in the receiver is overloaded by strong interference signals that are nearby.
