The following information is taken - and updated by me - from a FAQ on the Olympus DS-50 found on their web site at
http://www.olympusamerica.com/cpg_section/cpg_support_faqs.asp?id=1278#30 ***How can the blind and visually impaired set the time and date? The recorders' built-in audio cues can be used to enter the Time & Date settings. These same cues can be used to set Timer Recording and Alarm functions as well. Using the Keypad When executing a menu function that requires time and date setting, use the buttons on the recorder's four-way keypad to enter the settings. The settings are hour, minute, month, day, and year. Press the PLUS (UP) and MINUS (DOWN) buttons, respectively to increase and decrease the values. Press the REWIND (LEFT) and FAST FORWARD (RIGHT) buttons to move between variables. Press the OK/MENU button to complete the set-up and start the clock. Depending on the year of release for the machine, Each time and date variable has a baseline value, from which it is possible to calculate the number of times the PLUS (UP) or MINUS (DOWN) buttons must pressed to reach a particular value. On the DS-50, The baseline settings for hour, minutes, month, day, and year are respectively 12 AM, 00, 1M, 1D, and 2007Y. On the DM-520, the settings work the same, however the default year is 2009 rather than 2007, because the DM-520 wasn't released until 2009. I haven't properly explored, but I imagine the DS-71 will default to 2009 as well. The values appear on the recorder screen as shown below: When setting time and date variables the recorder emits distinct audio cues to determine that the variables are being changed. Pressing the PLUS (UP) button causes the recorder to emit a high-pitched beep. Pressing the MINUS (DOWN) button elicits a low-pitched beep. When a baseline value is reached from either direction, the audio cue becomes a chirp. The DS-50 (and others) digital voice recorder has a Voice Guide that speaks the menu items. However, it cannot speak the time and date or file names. When the DS-50 recorder is turned on for the first time , the Voice Guide function is enabled. If the Voice Guide is disabled, use the following steps to enable it: 1.Turn the recorder on by sliding the POWER/HOLD button downward. 2.Launch the menu by holding down the OK/MENU button in the center of the four-way keypad for 1 second. 3.Press the MINUS (DOWN) button 13 times to arrive at the Voice Guide setting in the menu. 4.Press the FAST FORWARD (RIGHT) button on the keypad twice. 5.Press the OK/MENU button in the center of the keypad once to enable the Voice Guide. 6.Press the REWIND (LEFT) button on the keypad once to return to the menu. Note that Details for activating the voice guidance on other machines, will differ. ***Setting the Time and Date 1.on the DS-50, If the Voice Guide has just been enabled and returned to the menu, press the MINUS (DOWN) button 7 times to arrive at the Time & Date setting. The Voice Guide will speak, "Time and Date Setting." 2.If the menu on the DS-50 has been newly opened, press the PLUS (UP) button four times to arrive at the Time & Date setting. [If you are using a different model, such as the DM-520 or DS-71, get to the time and date settings, and follow the below steps.] 3.Press the FAST FORWARD (RIGHT) button to open the Time & Date menu. The first variable to set is the hour. Press the PLUS (UP) button or MINUS (DOWN) button until the recorder chirps instead of beeps. The chirp means the hour variable has been set to 12 AM. 4.Press the PLUS (UP) button the number of times necessary to arrive at the correct hour value. Remember: The baseline value for hour is 12 AM. Therefore the first 11 button presses represent AM values. It may be quicker to press the MINUS (DOWN) button and count backward from 12 AM if the correct time is a PM value. 5.Press the FAST FORWARD (RIGHT) button to move to the minute variable. Press the PLUS (UP) or MINUS (DOWN) button until the recorder chirps instead of beeps. The chirp means the minute variable has been set to the baseline value of 00. 6.Press the PLUS (UP) button the number of times necessary to arrive at the correct minute value. If it would be quicker to count backward to the minute value, the MINUS (DOWN) button can be used to arrive at the correct minute value. 7.Press the FAST FORWARD (RIGHT) button to move to the month variable. Press the PLUS (UP) or MINUS (DOWN) button until the recorder chirps instead of beeps.The chirp means the month variable has been set to its baseline value of 1M, representing January. 8.Press the PLUS (UP) button the number of times necessary to arrive at the correct month value. If it would be quicker to count backward to the month value, the MINUS (DOWN) button can be used to arrive at the correct month value. 9.Press the FAST FORWARD (RIGHT) button to move to the day variable.Press the PLUS (UP) or MINUS (DOWN) button until the recorder chirps instead of beeps.The chirp means the day variable has been set to its baseline value of 1D, representing the first day of the month. 10.Press the PLUS (UP) button the number of times necessary to arrive at the correct day value. If it would be quicker to count backward to the day value, the MINUS (DOWN) button can be used to arrive at the correct day value. 11.Press the FAST FORWARD (RIGHT) button to move to the year variable. The year value is selected by using the PLUS (UP) or MINUS (DOWN) button. The baseline value on the DS-50 is 2007Y, the baseline value on the DM-520 and DS-71 is 2009 and is identified by a chirp. 12.Press the STOP button (center button on the right side of the recorder) to set the time and date settings and close the menu. Note that The same basic entry procedure is used in the Timer Recording and Alarm functions, but I don't recall if the past setting or the current date and time are the defaults. I have successfully set my clock and set timer record using this procedure - it sounbs particularly involved, but is actually not too bad with sound feedback, once you understand its basic operation.
