GENERAL

1.1 Introduction

The Frequency Select Handle provides the ability to select and display the operating frequency of
the receiver or transmitter on the Front Panel. Power is provided from a regulated +9.5 Vdc supply
and draws typically less than 4.0 mA in sleep mode.

1.2 Printed Circuit Board Numbering Convention

To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a
printed circuit board (PCB) numbering convention in which the last two digits of the circuit board
number represent the circuit board version. For example:
• PCB number 43-9120 10 indicates circuit board version 1.0.
• PCB number 50002- 02 indicates circuit board version 2.0.
All PCB's manufactured by Daniels Electronics are identified by one of the above conventions.
