Set 1st Dispenser Key Voucher
Key changes are occasionally carried out to maintain the security of a pre-payment system.
Unless the prepayment vending system and meter are both operating on the same key, vouchers
vended from that system will not be accepted by the meter.
To effect a key change, two vouchers (set 1st dispenser key and set 2nd dispenser key) need to be
issued and entered into the meter within a 5-minute period of each other. NB: Set 1st dispenser
key and set 2nd dispenser key vouchers may be entered in any sequence i.e. the 2nd dispenser
key voucher may be entered first.
Various ancillary functions e.g. clearing the meter log may be embedded into the
key-change process (refer to the STS specification).
