Emission Display Settings 1. press (FUNC) key to enter the setup menu, enable the extended menu. 2. rotate (SELECT) to call up the setup menu item No-061 ( SEL). 3. rotate (DIAL) to select an external instrument display: -PWR -ALC -MOD -SWR - -N / A -OFF Calibration method is as follows: 1. press (FUNC) key to enter the setup menu, enable the extended menu. 2. rotate (SELECT) to call up the setup menu item No-060 ( SEL). 3. rotate (DIAL) to select FS. 4. with a small flathead screwdriver to adjust the calibration adjustment hole rear, so the header pointer to full scale. 5. the calibration is complete! If you can not find the numbers 60, 61 menu, is this two radio hidden menu. Long press the F key to open the menu settings, menu set to ON, press the F key to open the exit to save the hidden menu. Note: The instrument has been calibrated delivery, but do not the bumps transit results in a static pointer is not , in this case the instrument can be adjusted at the mask-side self-zeroing screws appear black.

• Model-Specific Compatibility:‌ Designed exclusively for FT-857D and FT-897 transceivers, featuring direct plug-and-play connectivity without additional configuration. Displays critical parameters including ALC voltage and modulation levels.
• Multi-Parameter Monitoring:‌ Simultaneously tracks SWR ratios, supply voltage, and signal strength through clear analog display. Calibration adjustment port allows field tuning to maintain measurement consistency across operating conditions.
• Pre-Calibrated Functionality:‌ Factory-tested for immediate deployment with self-zeroing screw for transit-induced deviations. Supports FS calibration mode for full-scale reference alignment using included adjustment tool.
• Enhanced Workflow Integration:‌ Compact design (6.7x7x6cm) with 37cm cable enables flexible mounting positions. Accesses hidden menu items #060-061 for display mode selection between transmit power and receive signal metrics.
• Operational Simplicity:‌ Single- menu navigation with rotary dial selection. Includes pictorial setup guide for emission/receive display configuration, eliminating complex programming requirements.
