Charge Time: In instrument, typically 10 hours from empty at ambient temperatures
below 30 °C. To protect the battery, charging will be terminated completely at ambient
temperatures above 40 °C. At 30 to 40 °C charging time will be prolonged. With external
charger ZG-0444 (optional accessory), typically 5 hours.
Please note: It is not recommended to charge the battery at temperatures below 0 °C
(32 °F) or over 50 °C (122 °F). Doing this will reduce battery lifetime.
4.16 Warm-up Time
Warm-up Time: < 30 s after reaching equilibrium with the ambient environment and
switching on power.
4.17 Real-time Clock
Back-up Powered Clock Drift: <0.45 seconds over a 24-hour period
4.18 CE-mark and C-Tick mark Compliance
The CE marking is the manufacturer's declaration that the product meets the
requirements of the applicable EU directives RCM mark indicates compliance with
applicable ACMA technical standards – that is, for telecommunications, radio
communications, EMC and EME
