Keypad
The alphanumeric keys are used to enter the Logger Access PIN to gain access to the logger’s display and to
access logger menus. SymphoniePRO offers simplified programming through a USB connection to
SymphoniePRO Desktop Application software.
Navigation Keys
The navigation keys are used to move up and down lists, and to page forward and backward through items
displayed on the logger’s screen. Note that list items are also numbered and can also be selected by pressing the
keypad number of the item.
Display
SymphoniePRO has a 20 character, 4 line display designed for reliable operation in extreme cold conditions.
Display contrast can be adjusted for optimal viewing under different lighting conditions.
D-Cell Batteries
The logger’s basic functions run on standard D-cell batteries which are protected by a battery cover. Batteries
should be changed one at a time so that logging operations are not disrupted during the battery change. With
an iPack installed, the D-cell batteries primarily function as backup batteries for all logging functions in the event
that the iPack is removed or loses power.
Caution
An iPack should be used even in the case where communications are not required. The “Power Only” iPack is
recommended for this application. It is recommended that high quality alkaline batteries are used such as
Energizer or Duracell), and they should be changed at least once per year to avoid leakage and equipment
damage.
Wiring Panel Connector
The 62 pin connector should be securely screwed down using the thumb screws. Protect the pins by aligning the
connector well before inserting, and avoid plugging in the connector at an angle.
USB Port
The USB port is the primary programming access port used for configuration of the logger and iPack settings.
USB Cable
The SymphoniePRO system uses a standard USB Type B to USB Type A connection (standard laptop USB
connection).
Cable sold separately.
Clock Battery
A lithium battery powers the logger clock even if D-cell batteries are not present. This allows the logger to retain
date and time in the event of a reboot. Clock batteries will last 5+ years under normal use.
Clock Battery Warning LED
This LED illuminates if the clock battery has been installed backwards.
