Power
Main Power : 4.5 - 17V DC (4 internal D-size batteries)
External Power Connector : 5 to 17V DC
Clock Backup Battery Type : CR2032 (approximate 3-year life)
Internal Clock Accuracy : Temperature-Compensated Crystal with 3.5ppm drift
from -40°C to 0°C and 2.0ppm from 0°C to 40°C
Power Consumption : 0.5 mW (sleeping); 250 – 800 mW (recording)
Battery Specifications : The recorder uses four (4) standard D size disposable
alkaline batteries, rechargeable NiMH batteries, or batteries. Battery life can vary
widely depending on the battery type, brand, charger, temperature, and other
factors. The following battery life cycles are typical and assume 10-hour nights and
nap mode activated for full spectrum:
■
Alkaline batteries (estimated 12,000 milliamp hours at 1.5V each):
■
Full spectrum on 1 channel: 18 nights
■
Full spectrum on 2 channels: 15 nights
■
Zero crossing on 1 channel: 20 nights
■
Zero crossing on 2 channels: 15 nights
■
NiMH batteries (estimated 10,000 milliamp hours at 1.2V each):
■
Full spectrum on 1 channel: 12 nights
■
Full spectrum on 2 channels: 10 nights
■
Zero crossing on 1 channel: 13 nights
■
Zero crossing on 2 channels: 10 nights

Memory Cards
The four (4) memory card slots can be populated with at least one (1) and up to
four (4) memory cards of assorted capacities. The device supports all class 4 or
faster SDHC or SDXC cards.
Memory Sizes : Up to 1.0 terabyte (1024 gigabytes) supported total capacity using
256 GB SDXC memory cards for all four (4) memory slots. This is the maximum
currently available; higher capacities may be available in the future.
Formats : FAT32 for SDHC or exFAT for SDXC
Compression typically increases effective capacity by 40%.
