2.7.1 INTRODUCTION

NOTE: Keypad programming is available with full keypad (15-key) models only.

Keypad programming is available if the Keypad Programming option switch is programmed. It is then selected by simply pressing this switch (no password is required). Keypad programming allows conven- tional channel parameters such as the transmit and receive frequency and Call Guard squelch code to be changed. In addition, it allows several conventional mode timers to be changed. It cannot be used to repro- gram disabled channels or SMARTNET/SmartZone channels.
