ER-A Model Mode Switch, Keys and Job Codes Overview
Mode Switch, Keys and Job Codes Overview
The Sharp ER-A model programming consists of SRV (Service Mode) and/or PGM / PGM2 (Program Mode)
job codes.
Access to the modes is controlled by the mode switch and mode keys.
Job codes tell the ECR (Electronic Cash Register) what programming function to perform. Each job code
has bits that enable, disable, or define the settings for the respective job code.
The available Mode Switch, supplied Mode Keys and Job Codes vary by model.
Mode Switch and Keys
The key can only be inserted or removed when the switch is in the “REG” or “OFF” position.
The following diagram illustrates the various modes and operative range of the keys supplied with the
ECR. SRV and SRV’ modes are reserved for Authorized Sharp Dealers and Servicers and is only accessible
using a key labeled SRV. This key is not supplied with the ECR and must be ordered via the National Parts
Center (NPC). See your Sharp POS Support Directory for contact information.
The Mode Switch and supplied Mode Keys vary by model.
• REG MODE: This mode allows you to enter sales.
• OPXZ MODE: This mode allows servers to take X or Z reports of their sales information and can also
be used for employee functions.
• OFF MODE: This mode locks all operations of the POS terminal. When you select this mode, the
window will disappear. Touching any key turns the POS terminal ON.
• PGM1 Mode: This mode allows you to program those items that need to be changed often such as
PLUs (plus, prices, dept association), %, Servers/Cashiers.
• PGM / PGM2 Mode: This mode allows you to program those items that do not require frequent
changes such as date, time, departments, items, tax, servers/cashiers, terminal functions etc.
