GK615-X Attention! Before first use, the built-in battery for a time of 8-10 hours should be charged. Charging can be made via the included battery charger or if the GK 615 is in a car installed via the “Car Battery Cable 1KA615 (not included)” in the car.
GENERAL INFORMATION Introduction The portable VHF Station GK615-X is described in this Installation and Operation manual DV 16800.03. The portable VHF Station consists of the carrying case GK 615 and the transceiver AR 6201 - ( ). The transceiver AR 6201 - ( ) is described in manual DV 14300.03.
GK615-X The battery can be charged via the socket ext. D.C. The charging voltage can be varied between 10 V and 32 V. The charging time for a heavily discharged battery is approximately 8 hours. The nominal operating time for the portable VHF station is approximately 6 hours at a keying ratio of 1:10 normal ra- dio traffic) and transmitter output power of 5 W.

GK615-X Section INSTALLATION General remarks The installation of the portable VHF station depends on the type of vehicle and equipment design. It is therefore only possible to provide general guidelines in this section. Pre-installation check Prior to installing the portable VHF station in an vehicle, it should be inspected to determine whether any damage has been caused during transport.

GK615-X 2.3.2 Modification of antenna connection for installation in a vehicle The antennae connection is fitted on the front panel as standard. When fitting in a vehicle using the unit mounting bracket, it is best to mount the antenna connection on the rear. To do this remove both half shells and remove the bolts attaching the antenna socket to the front panel.

GK615-X Note: In this section the display content is mainly shown for transceiver working in 8.33+25 kHz mixed Mode. Dedicated pictures for 25 kHz Mode are not explicitly shown, because the display content is very simi- lar (They differ only in number of digits for frequency. Refer chapter 3.4).
GK615-X 3.1.2 Symbols shown on Display Symbol Meaning Intercom operation active (triggered by VOX or external IC key). Intercom operation via VOX is disabled. The transceiver is in transmit operation The squelch function is active. Noisy signals will be suppressed.
GK615-X 3.1.4 Channel Spacing Mode The channel spacing in which the transceiver shall work can be toggled by pressing by pressing “STO” and “MDE” keys simultaneously for at least 2 seconds. 8.33 kHz channel spacing (left) / 25 kHz channel spacing (right) In the 25 kHz Mode only 5 digits will be shown.
GK615-X Operating Frequency Channel Spacing Displayed Frequency Displayed Frequency (MHz) (kHz) in 8.33+25 kHz mixed in 25 kHz Mode Mode 136.9750 136.975 136.97 136.9750 8.33 136.980 136.9833 8.33 136.985 136.9916 8.33 136.990 Operating instructions 3.2.1 Receive and Transmit Operation 3.2.1.1 Receive Operation If PTT key is not pressed, the transceiver stays in receive operation.
GK615-X 3.2.2 Operation Modes The transceiver will always work in one of the four operation modes: - Standard mode - Direct tune mode - Channel mode - Scan mode The first three modes (standard mode, direct tune mode, channel mode) are called frequency selection modes and providing different user interface for convenient selection of the operating frequency.
Page 27
GK615-X In direct tune mode the active frequency is indicated in the top line. The battery voltage is indicated in the bottom line. The active frequency can be set directly by pushing and turning the rotary encoder. The changes beca- me active immediately.
Page 28
GK615-X 3.2.2.4 Scan Mode The Scan mode can be entered from all frequency selection modes by a long press of “ /SCN” key. The Scan mode can be left by a short press of the “MDE” key. After leaving scan mode, device will enter the standard mode.
GK615-X 3.2.2.5 Squelch In normal operation (no menu opened) the squelch can be toggled between on and off state by short press of the “SQL/IC” key. Squelch On (left) / Squelch Off (right) If the squelch function is active (on), noisy signals will be muted.
GK615-X If during storage procedure no action occurs during 7 seconds the transceiver returns to the previous mode without storing the frequency. The stored frequencies can be recalled in channel mode. 3.2.2.8 Automatic Storage Function The transceiver contains an automatic storage function operating in standard mode, direct tune mode and scan-mode.
GK615-X By a short press of the push button of the rotary encoder the next page Squelch is displayed. The acti- ve frequency is indicated in the top line of the display. On the bottom line is indicated ”SQUELCH” with bar graph and value.
GK615-X Appearance about every 5 seconds. The transceiver has detected an internal failure during normal operation. Depending on failure reason, the device may be still operable with degraded performance or not operable at all. Possible reasons for indication: - Out of specified environmental conditions - HW or SW failure inside the transceiver.
