He should actually be ok even with ER and no attenuators as minimum transmit power is -4.7 dBm and max receive power is -1 dBm (per cisco site). Just check optical power levels and see if they are in limits.
Well, the maximum allowable transmit power is +4 dBm so that's definitely blinding on a -1 dBm maximum receiver.
So unless one always checks each individual unit before trying it (think future spare replacements etc) it's better to go with worst combination of min/max values and then a 5 dB attenuator is a must.
