Service is available after warranty expiry at reasonable rates.
Lists the items included with the Stryker SR-447/497 transceiver package.
Plan transceiver and microphone bracket placement for convenient operation without driver interference.
Mount the radio securely using the bracket as a template, ensuring no behind-surface damage.
Operates on 13.8V DC negative ground; vehicle electrical system condition is crucial for performance.
Exceeding 15 Volts DC will damage the radio. Measure voltage before installation.
Connect positive wire to 13.8V source (switched preferred) and negative wire to chassis ground.
Uses standard PL-259 connector; recommends vertically polarized, quarter-wave antenna for best range.
Proper SWR adjustment is critical for performance and preventing radio damage.
A SWR meter is required for best performance tuning.
Method for adjusting antennas with setscrews to find the lowest SWR point.
Method for adjusting antennas that require cutting to achieve proper length.
Achieve SWR of 1.5 or below, with consistent readings across the frequency range.
Connect an 8-ohm, 4-watt external speaker for remote monitoring; internal speaker is disabled.
Connect an 8-ohm speaker to the PA jack for public address use; ensure speaker isolation.
Disabling modulation limiting circuitry can damage the radio and void the warranty.
Indicates the selected channel and allows changing transmit/receive channels.
Controls faceplate, meter brightness, and channel display color and dimming.
Shifts the operating frequency up by 10 kHz when activated.
Activates Noise Blanker (NB) or both NB and Automatic Noise Limiter (ANL) circuitry.
Controls the "roger beep" tone that sounds when the microphone is un-keyed.
Selects operating modes: AM, FM, or PA (Public Address).
Selects frequency segments A-H and adjusts transmit power output.
Monitors own voice and indicates high SWR via flashing light.
Displays receive signal strength and RF output power on two bars.
4-pin connector for mics; Squelch eliminates receiver background noise.
Controls for power/listening level, RF amplifier gain, and microphone gain.
Adjusts the delay and volume/number of echo repetitions.
Identifies and briefly describes the numbered controls on the front panel and their functions.
Recommends low-impedance dynamic or transistorized microphones for best results.
