Check that you have the correct password, and you are entering it in the correct upper and
lower case.
If still no success, the logger must be returned to the manufacturer, to set a default
password. Keep your password written down in a secure place.
When using the connect/disconnect hardware link, I get nothing in the rain log when the
connector is removed and replaced.
Check that the link is on the correct pins.
Check that the logger is either in "Rain Only Mode" (MO=on) or in "Rain + River Mode"
(MO=off) where the river mode is set for 4-20mA (DIP Sw 1-6 is on).
When the connector is removed the LED should flash 2 times and when the connector is
inserted the LED should flash 3 times.
The quadrature river encoder flashes the LED but nothing gets transmitted.
Check that the logger is in "Rain + River Mode" (MO=off) and in quadrature mode (DIP
Sw 1-6 is on).
Set the event flag (EV) to on to allow events to be transmitted. However the flag should
be off if the logger is connected to an intelligent modem.
Check that the multiplier in the river increment parameter (RVI=xx/mm) is set to a
reasonable number. Remember that mm quadrature changes represent one event.
The logger does not remember the time if I remove the batteries.
The Real Time Clock lithium battery must be flat. Return the logger to the supplier to
replace the lithium battery.
When the logger goes to sleep or I type BYE, I get a strange message.
The logger is designed to hang up a modem and clear it to a known state when going to
sleep. This is performed with the CLEAR sequence. Check the CLEAR sequences by
using the comms window (COM). The sequences can be nulled by entering CLEAR1= ,
CLEAR2= etc.
Periodically I get funny characters displayed (Modem not connected).
The logger may be attempting to send either a scheduled message or an alarm message.
Check the CALL and CLEAR sequences by using the comms window (COM) to check
communication settings. The sequences can be nulled by entering CLEAR1= ,
CLEAR2= etc..
Turn off the scheduled send command by entering SEND=00/0/00.
Turn off alarms by typing AL=off
