Assemble the push switch bracket, then emblem the PCB to the rabbet The * + "and * battery contacts should be vertically assemble to the rabbet of top cabinet. 8 Place the night side hook of bottom cabinet, then compress the left side. Screw the screw and other parts. Load the battery, assemble the battery compartment cover, ry | installation 1 Slide the battery cover stop and slide to lit battery cover 2 Pull the battery from the battery.
a Sensitivity Test Sensitivity is measured by field strength (bumf. The repeating test is essential condition for testing this specification. Sensitivity should be tested in the shield area that avoid interrupting by external noise. The value of sensitivity is a relative. It should be measured py compared tc a well operating pager. Tne test procedure as below 1) Connect the encoder output 10 external modulator pot of signal generator.
